Dear all,
I'm new to the list, so please excuse any faux pas.
I am hoping someone can help me with a problem I'm having using xtlogit, vce(cluster) with Stata 13.0.
I am using a panel of country-years and a binary DV. For theoretical reasons, I would like to lag all the IVs by one year. When I run the model without the lags, but with the clustered s.e.s, there is no problem, but with the lags, I get the error message "calculation of robust standard errors failed r(198)".
Is this a problem with my model, or just a limitation of xtlogit with a vce(cluster)? Any ideas on this, or ways to work around it would be much appreciated.
Thanks!
