Hi
in older versions of STATA, to obtain the marginal effects of the covariates we use the command "prchange". It permits to have the average effect of the variable on all categories and then on each category's probabibility. However, in STATA15, we can use the command margins, dydx(*) which gives the marginal effect of the covariate on each category, but not the average on all the analyzed categories!! Any ideas, please?
