Thank you very much. To clarify what I need: I have two different models that have been generated by splitting the sample. In order to test whether the variation in marginal effects of X variable across these two subsamples is statistically significant, I need to compute the Z-score. It is like comparing coefficients of one variable across two samples but I would like to do it for marginal effects as I make non-linear estimation.
Best wishes
Ebru
