Dear all,


1. I'm using gllamm as follows and at the end of iterations I dont get t-values
or standard errors. Therefore I cant use it without estimation statisctics.

gllamm depvar indepvar, robust i(nfirm) link(mlogit) fam(binom) nocons adapt
trace

Is it ok? Do you know how to resolve it?

2. when I want to include some random effect (33 firms in 23 years follow some
choices which take value 0, 1,2)I have done in this way. At the end of
iterations I get the note: Hessian matrix is not symmetric.maximization did not
converge.

gen const = 1
eq intercept: const
eq slope: year
gllamm depvar inddepvar, robust i(nfirm) link(mlogit) family(binom) nrf(2)
eqs(intercept slope) adapt nocons trace

Is it right?

I have written even previously to you regarding these questions but no reply so
far. So I would really appreciate your answer.

Edlira
