Dear Frauke,
the most basic hint would entail a question: did you write a .do file for
your model to be run? Recently, running with Stata 9/2 SE a 10,000
iterations Monte Carlo simulation with 8 independent variables, I noticed a
55% time reduction (from 1.20 hours to 45 minutes)using a .do file instead
of invoking each command line separately.

All the Best for your research project and Kind Regards,
Carlo

Hello,

I am running a logit modell for panel data (100.000 observations, 4 
independent variables, 4 controll variables). My problem is that stata 
needs almost 12 hours (or more) to run one modell. Does somebody knows how 
to increase the speed of the regression?

Best regards

Frauke Ruether
