Sample with only positive observations for all series

[ecardamone]

Hi,

I am trying to run a multivariate regression in a log-log format. Several series have negative observations. How can I tell EViews to estimate the equation for a sample that consists of only positive values for all series? My problem is that there are more than one series with negative values.

Thanks for help!

EViews does that automatically. Make sure you have the setting Genral->Options->Series and Alphas->Auto-series->Treat Evaluation Errors as NA

Oh that's great. Thanks so much! It worked.

But remember that if you change the variables in the regression, you may inadvertently change the number of observations.
