Re: Interaction term in PSPP

[Dr. Oliver Walter]

The /DESIGN subcommand of GLM works for fixed effects ANOVAs in PSPP, 
not for linear regression analysis. But Ana Messler asked for a way to 
build interaction terms in a linear regression model. In SPSS it would 
be possible because SPSS also gives the results of a regression analysis 
in addition to ANOVA results in GLM.
