Re: GLM factorial analysis

[John Darrington]

See the attached tar file.
expected.txt is what spss gives (apparently)
pspp.txt is what pspp gives.
fdequal.sps is the syntax, which has a test both with and without interaction.

I hope the problem is clear from this.

     Can you send syntax and output that shows the problems?
