There is one for 4 Groups with 1 covariate. Use that one and do not include the covariate.

I did not find it for for 4 Groups (1 Factor, 4 Levels), Zero Covariates.

I need for check to avoid error on my analysis. Please could you say me whether the followed codes are correct.

A) Group effect 1 -1 0 0 1 0 -1 0 1 0 0 -1

This will generate an F test for the group effect

B) 0.5 0.5 -0.5 -0.5

This looks like it will test a difference between Group1-and-2 vs Group3-and-4

Many thanks.

Stefano

Hi list,
please could you suggest me the group.effect.mtx and the file.mtx
relative to Null Hypothesis for 4 Groups (1 Factor, 4 Levels),
Zero Covariates. DODS or DOSS.
Thanks
Stefano
