Subject | st: Re: A fractional logit can't converge. Anyway, backed up results are useful for mfx? how? |
Date | Thu, 8 Mar 2012 13:14:42 +0100 |
I am using fractional tobit "glm depvar indepvar, link(logit) family(binomial) vce(robust)". I successfully used it in other two models, but in this case after some iterations Stata says "backed up" and cannot converge, then I create a table with the results (outreg), and still appears a resulting table with results that are consistent with my other two models, do those results makes statistical sense? I want to create then elasticities with "mfx" but I can't because the model did not converge, if those results produced with outreg (previous line) make a bit of sense, how can I create elasticities with them using Stata? Also, after typing the command appear "note: perc_mod_com has noninteger values", I do not understand why, as I think proportion variables should be 0 to 1. Following previous emails in Statalist, I tried delete some variables and I still couldn't solve it, OLS do not reject any variable, the model do not work trying to delete indep variables one by one, and I am trying more and more combinations, but it still does not work. Please somebody knows if this analysis can be carried on using another sofware? I need these results..
