[Limdep Nlogit List] Regression and Minimize

[Andreas Drichoutis]

Dear all, 
 
I'm trying to replicate the results of a multiple regression by using the
MINIMIZE command (see below the syntax I use). I get the same parameter
estimates but completely different std. errors. In specific, with the
minimize command, std. errors become extremely small and are not consistent
with the results from the regression. Why is this? (sample size is 350, if
it matters.).
 
Thanks,
Andreas Drichoutis
