Hey guys, I have got a question according to the programming of a white period test.

I have got a loop in my program that makes a regression. I know that I can change the panel options with Quick-estimate equiation-panel options-coef. covariance method-White period. But honestly I don't want to do this by hand for 300 regressions

Is there a possibility/code that solves my problem?!

Plz help!

If you can do it by hand, you can then look at View->Representations to see the command/program way of doing it.
