Dear all,

I have a question how to fix a missing wald chi square value. I have calculated xtlogit, re vce(cluster id). I have 6 degrees of freedom and 7 coefficients. So I know the origin of the problem that the value for wald chi square is missing. I just don't know how to fix the problem. The regression must be calculated with the function vce(cluster id), so omitting this function is not an option. Are there any alternatives? For example, is it possible to "artificially" increase the degrees of freedom?

Thanks for your help
