Subject:      Re: newbie:  Contrast for Bonferroni

Dear Albert,

             I think that the coding in GLM is to
set the last level to be 0. Using /SOLUTION on
the Model statement spells it out. So ...

CONTRAST '1 VS 2' DX 1 -1  0;
CONTRAST '1 VS 3' DX 1  0 -1;
CONTRAST '2 VS 3' DX 0  1 -1;

Gives all 3, and the statistics in solution
should confirm the last 2 as 1 vs 3 is the same
as testing that the 1st level is 0 etc.

Hope this is right,

Philip
