Any ideas about the program nllp_bs_gmm?
With the -if- condition 'if panel==3', are you trying to fit a model to
just one panel (firm) of your dataset? That won't work, because these
estimators require observations on multiple firms.
If that's not the problem, you can send your dataset directly to me
([email protected]), and I'd be happy to help you resolve the issue.
