Hello everyone,

I am a new user of stata, and I struggle with this particular issue:

I hope I will be clear enough.
I would like to test the accuracy of my model in the following manner:

Estimate my regression with (*N-1*) observations, and with the coefficients
obtained, predict the "*y_hat_i*" of the observation "*i*" I didn't use to
estimate the coefficients.
I would like to do that *N* times, in order to have *N* "*y_hat_i*" (*i=1,
... ,N*).

Than I could compare the "*y_hat_i*" with the real "*y*", and test the
accuracy of my model (mean errors, median error, standard deviation etc.)

I appreciate your time,

Luke
