st: xtnbreg discontinous region encountered after rescaling
Date

I am running a series of fixed effects negative binomial panel
regressions (xtnbreg, fe) on different dependent variables. I have
encountered some specifications that do not converge or cannot be
computed due to discontinous regions before. However, one specific
regression that worked fine suddenly returns
discontinuous region encountered
cannot compute an improvement
r(430);
after I rescaled one independent variable. I didnt change anything
substantial, just divided by factor 100 - how is that possible?
thanks very much,
Hl.
