Hi,
Could anyone tell me the difference b/w suprob and biprob commands? I
tried both commands but I dont get any results. It seems that
loglikelihood does not become concave. why. I specified a labor force
participation equation and a choice model b/w self-employment and
wage-employment. I expect it to converge, to fit quite OK. I also use
partial option since the positive outcome in my second equation is
possible only when the first equation is positive, that is lfp=1, Why
dont I get the results. Please help
Thank you
