Thanks a lot to all who have responded. I must add that I'm not only a PSPP novice, my knowledge of (and, admittedly, my interest in) statistics in general is very small. I'm basically looking for statistical recipes that I can apply. What I actually want to do is to replace the mediocre PDF output of SPSS (which my daughter was using to create images for her MD thesis – I don't know SPSS and she has no longer access to it, so there is no chance to improve the created bar diagrams directly) with the route .SAV file -> PSPP -> CSV -> LaTeX pgfplots mainly to be able to recreate the diagrams programmatically, without using a GUI (I guess that R would be probably a better choice for that purpose, but I don't know this either). In other words I'm just poking with a stick in the dark... Here is the command that her group was using on SPSS. GLM Var1 Var2 Var3 BY Group WITH Age /WSFACTOR=Location 3 Polynomial /METHOD=SSTYPE(3) /PLOT=PROFILE(Group*Location) TYPE=BAR ERRORBAR=CI MEANREFERENCE=NO /PRINT=DESCRIPTIVE ETASQ /CRITERIA=ALPHA(.05) /WSDESIGN=Location /DESIGN=Age Group. [There are two groups, with approx 15 cases each.] The diagram shows bars for the mean values of Var{1,2,3} together with error bars indicating the CI.
