Wald test for comparing coefficients across groups
...teraction is significant.
So, can someone provide the code or point me to a place that a similar issue might already have been discussed, for the case of doing a Wald test to compare the beta coefficients of specific IVs
of interest between different regressions/groups (same model used for all thesegroups)?
Thanks in advance,
Kostas
