Hi all, I'm working on demand system estimation using Stata 10.1. The end objective is to be able to measure the welfare effects of price and income changes. So, by design my variance matrix from computation of elasticities, which I'm going to use for welfare analysis, is non-symmetric. Consequently, I couldn't get standard errors for my welfare change measures. I get a coefficient table with all missing standard errors when attempting to extract coefficients using "nlcom" command. Does anybody know if there is a way of forcing Stata to display non-missing standard errors.
