Addendum: If I select Sample > Drop observations with missing values, I get the message "No observations would be left" which is not the case (i.e. deleting cases listwise would not result in an empty sample).

I realize this may be a different issue.

Trying to run a Poisson regression of count data vs a number of covariates, I found out that if a covariate has missing values gretl complains that missing values were encountered.

Is it possible to instruct gretl to just ignore cases with missing values listwise?

If not, this is super annoying. I may be missing something.
