Fit Model Custom Test Coefficients
I am trying to jury-rig a post-hoc pairwise slope comparison with a custom test. I read through the documentation on custom tests but still don't understand how I am supposed to determine what coefficients to use to set up the tests. I have three treatments [PT CS OF] and want to do a pairwise test of the interaction between these treatments and a continuous variable [Duration]. If I understand th...
