Post-estimation results manipulation: Stata vs. R

January 26, 2011
By

Stata's new "margins" command is as powerful as "Zelig" package for R for the purpose of conducting post-estimation manipulation of the results (e.g. producing predicted probabilities, confidence intervals, etc.). While "margins" uses delta method, "Ze...
