* http://www.spss.com/tech/stat/kw/Kw67/tech67.htm *QUESTION: I have a variable in my file which represents different groups. I want to randomly select a specific number of cases from each group. How can I do this? * ANSWER: Assume the grouping variable is called "group" for the purpose of this exercise. The syntax below will select two cases from each group. COMPUTE tempvar=UNIFORM(10). SORT CASES BY group tempvar (A). SPLIT FILE BY group. COMPUTE tempvar=1. CREATE filter=CSUM(tempvar). RECODE filter (1 thru 2=1) (3 thru highest=0). FILTER BY filter. EXECUTE
