The Anova capabilities of PSPP are currently rather limited. Oneway anova is supported through the ONEWAY command. The latest master also has the command GLM which, when complete, will be able to perform everything you are looking for. Unfortunately, at the moment, it can only do "latin squares" designs.
Jason Stover is working on the last bit necessary to allow a full factorial univariate anova. Hopefully, that will be finished soon. From there, I think it'll be straightforward to extend to the multivariate case. I'm not sure what would be involved to get it to accept covariates, which would do your ANCOVA/MANCOVA requirements. Maybe you would like to look into that? If you want to contribute code to PSPP, you should also take a look at the PSPP developer's guide (which is in the tarball), and at the GNU Coding Standards http://www.gnu.org/prep/standards Thanks for your interest in PSPP.

I am a student in both Math and Computer Science, and although I feel confident in C, I am learning about ANOVA/MANOVA and ANCOVA/MANCOVA in my classes, which is what I would like to implement over this coming semester. I would also need to learn GSL while coding these. If you think my code could help, let me know if you have any more specifics on the struct that I should use to store the results of my routines besides what I will be able to figure out by browsing other back end examples PSPP uses. Is there anyone else working on this? -- PGP Public key ID: 1024D/2DE827B3 fingerprint = 8797 A26D 0854 2EAB 0285 A290 8A67 719C 2DE8 27B3 See http://pgp.mit.edu or any PGP keyserver for public key.
