Dear Gretl users,
I have a question about system estimation and a (possible) bug report.
The question is: is it possible to include weights for observations when
estimating a system of equations in gretl (with sur method for example)?

I've read in the command reference that the supported estimators

are ols, tsls, sur, 3sls, fiml and liml. However, if I estimate the system using the

"simultaneous equations" dialog box, there is also wls as one of the proposed estimators

(but it's not possible to specify a weight variable, so maybe it does not perform a

weighted regression after all).

The possible bug occurs after the estimation of a system using method SUR. In the results

window, the command "Tests -> Normality of residuals" is active, but nothing happens when

I click on it (gretl does not crash either). I'm running gretl 1.10.1 on Windows 7,

but I had the same problem with the previous release.

Thank you and best regards

Simona
