As Dr. Water says, syntax is a solution. The steps would be to (1) paste the desired analysis and then (2) edit the syntax to insert the "IF" statement above it.
You also need to decide if you want to "permanently" delete the non-selected cases or not. If I have a long series of analyses, I might select cases (say valid cases) and save them (or use a filter). But Hollenbach describes analyzing subsets of the dataset and in that case I often find the temporary command to be helpful. The syntax for _each analysis_ would look like this: temporary. select if( region = 1 or (region=1 and id=3)). freq ... You would highlight all three statements and run them. The "temporary" command causes the selection to be in effect only for the next analysis. You repeat the "temporary" and "select if" for each analysis (or, again, use a filter). BTW, I honestly think just typing the syntax of the "select if" is easier than using the GUI. -Alan On 1/18/2017 9:53 AM, Aj Hollenbach wrote: > Hi PSPP Users, > > I am transitioning from SPSS to PSPP and am having some troubles with > case selection.
