Riccardo's script for fixed effects Poisson Regression

is attached with the only one line added at

the bottom. My system is 32-bit Ubuntu 15.10

The line is just

varlist --accessors

The script before is added to explain the

situation, since 'varlist --accessors'

causes no problems in other known to me

settings.

P.S. Analytical derivatives give perfect

coincidence with Greene table, mentioned

by Riccardo, so only technical work is left
