## spss do if multiple conditions

values, except for some circumstances. A similar but dialog is shown by to select (filter) observations for analysis). Let's first assume that you have a single condition. LIST. Some SPSS users may be familiar with DO IF. now whether the next condition is also met. Several options are offered: All Cases (default initial setting) Use it to remove a filter you have defined. Logical expressions. They can be nested within LOOP—END LOOP structures, and loop structures can be nested within DO IF structures. Ask Question Asked 8 years ago. Now if you write: IF (gender EQ 1 AND famst EQ 3 OR famst EQ 4 OR famst EQ 5
We'll dichotomize variables v4 to v6 by changing values 1, 2 and 3 into 0 and values 4 and 5 into 1 as implied by recode v4 to v6 (1,2,3 = 0)(4,5 = 1). Example. In this tutorial, we will talk about the options are available to facilitate data filtering.Navigate to Data > Select Cases There are several options in this Select Cases box. COMPUTE #TAKE_IT = 1. To select cases for inclusion into analysis call up . COMPUTE Bonus = 0. of MISSING to denote system missing values. Hi, I am new on SPSS, I hope you can provide some insights on the following. The way SPSS deals with missing values in IF conditions is not always easy to understand. If you use multiple IF commands instead, the last condition met by each case takes effect. Viewed 5k times 1. END IF. Conditional transformation create (or change) data values only IF a certain condition is true. SPSS multipurpose tutorials. The best thing
Thanks in advance for your help! IF is a conditional COMPUTE command whereas DO IF can affect other transformations -such as RECODE or COUNT- as well. An SPSS data file contains variables, which are like columns on a spreadsheet, and observations (or cases or subjects) which are like the rows on a spreadsheet. Before we introduce you to these six assumptions, do not be surprised if, when analysing your own data using SPSS Statistics, one or more of these assumptions is violated (i.e., is not met). These 3 variables represent data gathered from 3 separate interview dates in a prospective cohort. In this case, we can first use a RECODE command only for cases whose gender is female. The logical expression tests whether STATE equals IL and CITY equals 13. I used this syntax, but it returns with 0 valid and all missing values. These conditions are statements (or chains of statements) that evaluate as … The syntax below demonstrates this, using employees.sav. END IF. For the majority of data management I do in SPSS, the brunt of the work is likely done in under 10 different commands. In SPSS the command to do this is called Compute. IF (gender EQ 1 AND (famst EQ 3 OR famst EQ 4 OR famst EQ 5)
Would highly appreciate your thoughts on this. Logical expressions. IF is a single line command while DO IF requires at least 3 lines: DO IF, some transformation(s) and END IF. If DO IF—END IF is used, control passes out of the structure as soon as the first logical condition is met. Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. SPSS has similar function but it is called “Select Cases“. DO IF (YearHired GT 87). *Required field. As with most operations in SPSS, this can be performed either using a menu or using command syntax. For example, if we only want to use data where Salary is larger than 20000, then we type the followings in the text box. Can you suggest a good way on how to do this? COMPUTE newvariable=1. If two conditions are concatenated by AND, the whole expression is true only if both conditions are met. Either adjust the DO IF conditions or replace the missing values before running your syntax. END IF. /*White female + COMPUTE Gender_Ethnicity=3. 2 The default specification for a recode is to Include all cases. For a thorough analysis, however, we want to make sure we satisfy the main assumptions, which are. The syntax below shows how to use it. They all have the same variable fields but for one variable in consideration for some data sets that variable field will not be populated. This video demonstrates how to recode variables in SPSS with specified condition for inclusion of records. END IF. We may want to use different cut off points for male and female respondents. It is usually highly recommended to use parentheses to clarify the priorities of clauses. variables. In Excel, you can apply Autofilter and enter criteria to select data what you want. serves as a shorthand that may help to make syntax more transparent especially
These conditions are specified in a logical expression. I could look also fix the data for you but I'd have to charge for doing so. you could shorten your syntax a lot by using IF instead of DO IF. I suspect you can enter more complex conditions on the resulting /SELECT subcommand as well. Dichotomize Multiple Variables SPSS Recode Example 2. Rather, you can have SPSS create it/them temporarily by placing an asterisk between the variables that will make up the interaction term(s). We may want to use different cut off points for male and female respondents. Dichotomize Multiple Variables SPSS Recode Example 2. That is, there must be valid values for each input variable in order for the computation to work. The syntax below demonstrates this, using employees.sav. 3. Select the first option If condition is satisfied > click on If … button . In fact, if there is a missing value for one or more of the input variables, SPSS assigns the new variable a missing value. The DO IF and ELSE IF lines tell SPSS to perform the nested computation if certain conditions are true. This is because the clause is true in any the following cases: and thus the following persons will get a value of "1" in the variable singlemo: Note that the way SPSS behaves is exactly in line with modern logic. COMPUTE Bonus = .12*Salary87. perhaps, that the last ELSE IF condition may be substituted by the simple keyword ELSE. LIST. What I want to do is to create another column in data frame dat called suit. To specify the conditions under which the recode should be applied, however, you will need to click Include if case satisfies condition. If thereare several conditions, you may specify wheth… If this is the case, the variable that is named immediately on theleft of the equal sign will get the value on the right hand of the equal sign. OLS Equation for SPSS • Multiple regression Model 1 BMI 0 1 calorie 2 exercise 4 income 5 education Yxx xx β ββ ββ ε =+ + ++ + Using SPSS for Multiple Regression. The command. DO IF variable1 = 0 and variable2=0 and variable3=0. You could check for it by using something like. You will use one or more variables to define the conditions under which your recode should be applied to the data. If I shorten the syntax to IF, END IF turns up red (error) towards the end of the syntax. However, don’t worry. I have a data base of patients which contain multiple variables as yes=1, no=0. will call up this dialog: Enter a Target Variable, i.e. In addition, the arithmetic functions that are explained in the Compute
IF (STATE EQ 'IL' AND CITY EQ 13) COST=1.07 * COST. given by the students are correct. In its simplest form, DO REPEAT simply iterates over a list of variables and can apply computations to those variables. if several transformations have to be performed given a certain condition and even more if the transformations
Then if a case has value 1 in vara and a missing value in varb, it will have "value" in
In the lines after DO IF or ELSE IF any kind of data transformation
SPSS however does not like me doing so (I am probably missing something in the syntax, but I do not know what). In this case, we can first use a RECODE command only for cases whose gender is female. Â Â compute q1r = q1 eq 4. This is not uncommon when working with real-world data rather than textbook examples, which often only show you how to carry out a three-way ANOVA when everything goes well! I made a habit of adding them whenever I move to another set of transformations (e.g. Demonstration - SPSS draft output: * ..... . IF (STATE EQ 'IL' AND CITY EQ 13) COST=1.07 * COST. I am still having problems with combining these 3 variables. I read that conditional processing in SPSS macros takes this form: !IF (expression) !THEN statements !ELSE other statements !IFEND However when I try to apply this to my datasets - I can't make it work. IF checks whether the condition(s) that is (are) listed after the
This is where you do the work of selecting female only cases. You first will check whether a person is female (say, gender EQ 1) and if she is never married or divorced or widowed (say, famst EQ 3, 4 or 5); and if this is true, you have to check whether the number of children this person has is greater than 0 (nkids GT 0). These results indicate that the overall model is statistically significant (F = 5.666, p = 0.00). Using the menu. DO REPEAT is one of those commands, and I figured I would show some examples of its use. I do not have string variables but I do have missing values. SELECT IF TESTVAR EQ "testval". The IF command is used rather than the DO IF—END IF structure in order to test both conditions on every case. Before we introduce you to these six assumptions, do not be surprised if, when analysing your own data using SPSS Statistics, one or more of these assumptions is violated (i.e., is not met). The IF command is used rather than the DO IF—END IF structure in order to test both conditions on every case. P.s. /*White male + COMPUTE Gender_Ethnicity=1. 2. This option allows you to select data based on criteria. Type Salary > 20000 . When variables are compared to numbers or other variables, the following keywords or signs can be used: Several conditions (comparisons) may be concatenated by AND (symbol:Â &) and/or OR (symbol:Â Â¦). We will talk about each option in the below section. COMPUTE newvariable=9. Here is what you get when selecting the IF button to specify a conditional transformation. Note,
In addition, you may specify, instead of a condition having to be met, a condition that must NOT (symbol:Â ~) be met. You will use one or more variables to define the conditions under which your computation should be applied to the data. Â Â AND nkids GT 0) singlemo = 1. SPSS multipurpose tutorials. If there
ELSE IF variable1 = 7 and variable2=7 and variable3=8. If cases meet more than 1 condition, the first condition prevails when using DO IF - ELSE IF. If this is the case, the variable that is named immediately on the
Then add the expression to the Numeric Expression field. Execute. DO … clauses. 2. To perform transformations involving logical tests on two variables, you can use nested DO IF—END IF structures. There must be an END IF command for every DO IF command in the structure. Relations cannot be abbreviated. I haven't tried it. All are continuous. IF (vara NE 1 OR varb NE 1) newvar = value. Example. They all have the same variable fields but for one variable in consideration for some data sets that variable field will not be populated. If cases meet more than 1 condition, the first condition prevails when using DO IF - ELSE IF. SPSS COMPUTE IF argument1 AND argument2 AND argument3(Graduate student Howard Brandon came to me for help with his masters thesis. that the expression after DO IF or ELSE IF is true. will call up this dialog: Enter a Target Variable, i.e. COMPUTE newvariable=0. Is it possible to nest conditional statements in SPSS? DO REPEAT TESTVAR = VAR1 TO VARn . may follow. This is called listwise exclusion. ELSE IF variable1 = 1 and variable2=1 and variable3=1. Exam Score is still selected as our DV, and Revision Intensity and Subject Enjoyment are entered as the predictors (or IVs). ELSE (IF) ... END IF clause permits to perform one or more transformations on condition
Sometimes data files contain information that is superfluous to a particular analysis and you might want to make a data file that has just the variables and/or observations you need for that analysis. Relations cannot be abbreviated. The syntax is: If vara has a value that is not smaller than 1.7 and not bigger than 4.8, the variable newvar will have the value that is specified on the right hand, i.e. Assume you write: IF (vara EQ 1 OR varb EQ 1) newvar = value. ELSE IF variable1 = 9 and variable2=9 and variable3=9. to be done vary with a series of different conditions. COMPUTE newvariable=7. The DO IF—END IF structure sets Stock equal to New when ITEM equals 0, to Old when ITEM is less than or equal to 9 but not equal to 0 (including negative numbers if they are valid), and to Cancelled for all valid values of ITEM greater than 9. I did try doing 'check' and it confirmed valid values and missing values. The conditions after the IF clause usually compare one or several variables to numbers or othervariables. You need to do this because it is only appropriate to use multiple regression if your data "passes" eight assumptions that are required for multiple regression to give you a valid result. Enter multiple reponses in SPSS with this quick video tutorial. Â Â compute q3r = q3 eq 1. Note that in SPSS, you do not need to have the interaction term(s) in your data set. Note, however, that the command. to a professor having given his students two versions of a test and now having his computer judge whether the answers
This is not uncommon when working with real-world data rather than textbook examples, which often only show you how to carry out a two-way ANOVA when everything goes well! What I want to do is to create another column in data frame dat called suit. These results indicate that the overall model is statistically significant (F = 5.666, p = 0.00). A similar but dialog is shown by to select (filter) observations for analysis). Alternatively, select cases to be deleted by using the NOT operator: SELECT IF NOT (grade=1). Maybe there's something wrong with my software? Hi, I am new on SPSS, I hope you can provide some insights on the following. Most data editing in SPSS is unaffected by filtering. That is, you can check whether a variable has one out of several values, as in: IF ANY (vara, 1, 7, 8, 16, 18) newvar = 3. Hi, I am new on SPSS, I hope you can provide some insights on the following. All system missings could also occur if your values have hidden decimals. Then add the expression to the Numeric Expression field. In SPSS the command to do this is called Compute. In this case, the ensuing
compute check = (variable1 = trunc(variable1)). Note that in SPSS, you do not need to have the interaction term(s) in your data set. IF clause is (are) true. Using the menu. As in many other commands, missing values may be addressed explicitly, however. An important thing to notice here is that ELSE does not include cases for whom previous conditions could not be evaluated due to missing values. But what if you need to test multiple conditions, where let’s say all conditions need to be True or False (AND), ... OR and NOT to set Conditional Formatting criteria with the formula option. COMPUTE Bonus = .1*Salary87. The value of Stock remains blank if ITEM is missing. In addition, the arithmetic functions that are explained in the Computesection may be used, as in the expression "abs(vara)" used above. The logical expression can contain relational operators, logical operators, ... or more complicated arithmetic expressions. I am running a multiple regression analysis for 2 predictors (parental conditional positive regard, parental conditional negative regard) and 1 DV (resilience). The logical expression can contain relational operators, logical operators, ... or more complicated arithmetic expressions. Â© W. Ludwig-Mayerhofer, IGSW | Last update: 26 Jul 2004, all women who were never married (whether or not they have kids), all persons who are divorced (no matter whether they are female or not and no matter whether they have children or not). If there's no hidden decimals, "check" should result in a column of 1's which you can check by. + END IF. GET FILE=TESTDATA. Dazu rufen wir das Dialogfeld Lineare Regression und wählen die Optionen auf, wie unterhalb beschrieben: Um eine multiple lineare Regression auszuführen, gehen wir zu A nalysieren > R egression > L inear… Es erscheint das folgende Dialogfenster. From the Home tab, click Conditional Formatting > New Rule. We'll dichotomize variables v4 to v6 by changing values 1, 2 and 3 into 0 and values 4 and 5 into 1 as implied by recode v4 to v6 (1,2,3 = 0)(4,5 = 1). An SPSS data file contains variables, which are like columns on a spreadsheet, and observations (or cases or subjects) which are like the rows on a spreadsheet. For more on this, see SPSS Recode - Cautionary Note. It can be considered to be similar to the one-way repeated measures ANOVA, but for a dichotomous rather than a continuous dependent variable, or as an extension of McNemar's test. Sometimes data files contain information that is superfluous to a particular analysis and y… We can see in this example that the first three subjects were males and the last four subjects were females. SPSS Multiple Regression Analysis Tutorial By Ruben Geert van den Berg under Regression. linearity: each predictor has a linear relation with our outcome variable; The cases that do not meet the filtering condition are "barred", as it were, from the analysis; however, they may re-enter at any time. Â Â (vara gt 2 and abs(varb) le 7)) varz = 0. You do not need to add text labels – SPSS Statistics will work fine without them – but it can provide extra clarity when analysing your data (especially as text labels are often used in the output instead of the numbers – this helps greatly). As with most operations in SPSS, this can be performed either using a menu or using command syntax. You can see here we’ve got “Sex = 0”, which tells SPSS that it should only select cases where the value of the variable Sex is 0 (Female = 0, Male = 1). The conditions after the IF clause usually compare one or several variables to numbers or other
SPSS transformations between DO IF ... and END IF are applied only to cases (rows of data) that satisfy one or more conditions. For using such commands on subsets of cases, see FILTER, SPLIT FILE and SELECT IF. When I revert back to the syntax using DO IF, the whole thing runs with the output valid = 14211, missing = 0 but all the data is coded as 9. Imagine we already know that in the population as a whole the average amount of time i… using keywords AND and/or OR. Most of what is important about this command can be found in the example on top of this page. we haven [t shut SPSS down since running our multiple regression (in the previous tutorial), SPSS remembers the options we chose for running our analysis. The data we’re using for this tutorial comes from a hypothetical study that examines how long it takes people to fall asleep during a statistics lesson. Several conditions may be be concatenated by AND and/or OR clauses. For instance, you may be looking for mothers in your data who are not married. To delete certain cases from an analysis, use the SELECT IF command and select cases by providing selection conditions. This looks strange; it works because the multiple SELECT IF statements it generates, 'and' together. I read that conditional processing in SPSS macros takes this form: !IF (expression) !THEN statements !ELSE other statements !IFEND However when I try to apply this to my datasets - I can't make it work. operator, missing values may cause no problem, but only when one of the conditions is true. SPSS COMPUTE IF argument1 AND argument2 AND argument3(Graduate student Howard Brandon came to me for help with his masters thesis. Before we introduce you to these six assumptions, do not be surprised if, when analysing your own data using SPSS Statistics, one or more of these assumptions is violated (i.e., is not met). IF ((varx eq 1 and not missing(varu) and vari eq vark) or
Thus, if a case has a
The final syntax example demonstrates this by creating a birth decennium variable using XDATE. Â Â compute q2r = q2 eq 5. However, don’t worry. Another is a DO REPEAT construct. However, don’t worry. The DO IF command
Cochran's Q test using SPSS Statistics Introduction. ELSE IF (Dept87 EQ 1). we haven [t shut SPSS down since running our multiple regression (in the previous tutorial), SPSS remembers the options we chose for running our analysis. Anybody knows what I'm doing wrong? I also tried saving a work file with only these 3 variables, plus the id number and some other basic data of participants. So I want SPSS to change variable 1, 2 and three if Var1=X. So they get a system missing value on the new variable. Before we introduce you to these six assumptions, do not be surprised if, when analysing your own data using SPSS Statistics, one or more of these assumptions is violated (i.e., is not met). /*Do whites + DO IF (Gender EQ 2). These exclude most commands that generate output such as FREQUENCIES and DESCRIPTIVES. In any case, I think these built-in filters can be very handy and it kinda puzzles me they're only limited to the 4 aforementioned commands. First off, are you sure none of variable1 to variable3 are string variables? ☺️. The keyword SYSMIS may be used instead
Next, we'll use a different RECODE command for males. The syntax below sketches this idea. DO IF version eq 1. Rather, you can have SPSS create it/them temporarily by placing an asterisk between the variables that will make up the interaction term(s). newvar. EXECUTE. This is not uncommon when working with real-world data rather than textbook examples, which often only show you how to carry out a three-way ANOVA when everything goes well! ELSE IF version eq 2. DO REPEAT TESTVAR = VAR1 TO VARn . DO IF (Ethnicity EQ 5). IF is a conditional COMPUTE command whereas DO IF can affect other transformations -such as RECODE or COUNT- as well. Usually, the variable to which a value is assigned IF the condition is
AND, OR and NOT are called logical operators. Say we'd like to convert people's monthly income into income classes. SPSS Select Cases – If condition is satisfied. He wanted to dichotomize three continuous variables and then assign cases to groups (profiles) based on their scores on those dichotomized variables. COMPUTE #TAKE_IT = 1. ANY is an abbreviation for a series of OR clauses related to one variable. Â Â AND nkids GT 0) singlemo = 1. you will find an amazing number of single mothers in your data. To test the next couple of assumptions, CLICK on the Statistics option now. I am trying to recode multiple variables with one IF statement. Â Â compute q1r = q1 eq 1. Â Â compute q2r = q2 eq 3. When you do this you can omit the IF function and use AND, OR and NOT on their own. This is because one of the conditions is met, namely, vara EQ 1, and SPSS does not care
Active 4 years, 1 month ago. glm write by female ses. Warning - Data Editing with Filter. I have a data base of patients which contain multiple variables as yes=1, no=0. He wanted to dichotomize three continuous variables and then assign cases to groups (profiles) based on their scores on those dichotomized variables. section may be used, as in the expression "abs(vara)" used above. the RECODE command, alone or in combination. SPSS Output Tables. For example, (A EQ 2 OR A EQ 5) is valid while (A EQ 2 OR 5) is not valid. document.getElementById("comment").setAttribute( "id", "a37c8f4ec439e233dd2353b63859349c" );document.getElementById("cf48453165").setAttribute( "id", "comment" ); Hi Ruben, I have a question. This means that the commands that follow are carried out only for cases who 1) satisfy the current condition(s) and 2) don't satisfy any of the previous conditions. ELSE IF
