Unbiasedness estimator, simulations

[Enrico Azzini]

Good morning, maybe this would be a useless question but I would like to resolve my doubt. I was wondering how perform a test in order to check if my estimators are unbiasedness. From what I read in the book "microeconomics for stata" to check it out it's necessary to simulate n_times the model, however I didn't understood the command to do this moreover in the book this section is related to the Monte Carlo experiment so I'm not sure that it's applicable in every situation. I also read that to check for omitted variable bias I can use the command ovtest or I can check them adding in the regression the predicted values and the sq. predicted values. Can someone clarify me the issue please?
Thanks a lot for your attention

Enrico:
as far as your second query is concerned, see -linktest- enty and related methodological notes in Stata .pdf manual.
