Re: GLM

Hi Mark,

Thanks for dropping in.

Yes, a "repeated measures" design capable GLM would be great. As would an 
anacova
and "mixed models" capable one.  A number of requests have been made for these.

My main problem is that I am not familiar enough with the theory of how they 
work,
and there seems to be very few tutorials on the subject (except those which just
tell the reader to use SPSS to get the answer).

If you can help on that front it would be great -  I or someone else can do the 
coding.

The GUI is a relatively straightforward (albiet boring) exercise.

     Hi John,
     
     Sorry for the delayed reply (I was on vacation and away from email). While
     I'd love to help with this, I very rarely have time for this kind of
     programming. Nonetheless, I've signed up for the pspp-dev email list, and
     could probably help with a bit of testing. There are several months of the
     year that I can't be relied on for this, though.
     
     I think the bare necessity for making GLM useful in my lab is to enable the
     /WSFACTOR and /WSDESIGN subcommands, though the /EMMEANS one is also
     important (with the COMPARE parameter for wsfactor post-hocs).
     
     It would also be nice to get the GUI part of GLM in place (copying SPSS, as
     other commands do). My typical approach (and what I teach to students) is
     to use those first and paste syntax, which you can then modify (which tends
     to be easier than using syntax from scratch).
     
     I noticed there was a request for ANCOVA today, and this would also be
     better supported with a more fleshed out GLM command (and GUI),
     specifically the WITH part of the main command.
     
     Mark
