I have a question regarding calculating marginal effects (change in the probability due to a one unit change in x) for a probit or for that matter any discrete choice model. Does R have a function that will essentially do this:
dE[y|x] ------- = f(x'beta)*beta dx
Stata has a command called "mfx" that calculates the marginal effects at the mean (of the x values). Is there a R equivalent to mfx?
Thanks, Renuka. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
