Hi Stata users
recently, several articles have been published on graphical tools for testing interaction in regressions with dycothomous dependent variable (i.e., logit and probit). They say that simply looking at the significance of the interaction coefficient is not enough, and that one should look at graphs to establish whether an interaction effect is significant.
Is it the same also for poisson and zero-inflated poisson models? Or - in these latter models - I can simply look at the significance of the interaction to state that the interaction effect is significant?
Thanks!
