Hi Sven
the specification was just pushing data and parameters to their limits with specific lags of  1 3 6 and 9 years specified in the 2 dependent variables to try to pick up some cyclical elements in the data and  with only 22 observations. I will try it dropping the lag 9 later (I have other ARMAX results I don't want to risk losing at present until I have finished the session) to see if it makes the difference between crash or go!
Windows 10 OS. However, i would have expected some failure messages, not a complete crash.

Hi
A warning.
the Model  Var Autoregression in the GUI can crash out Gretl -no error message re estimation no. of variables too few or anything -it just disappears from the screen. So all preceding work done without the outputs saved in the session (not necessarily only from  previous Var autoregressions ) will be lost.  Mine is the latest Gretl  version.

Hi,

I cannot replicate this on Ubuntu 20.04 with latest git. Brian could you provide a detailed step-by-step guide what you do? Also, which OS are you using?
As per the changelog (http://gretl.sourceforge.net/ChangeLog.html) there is one known crash bug currently since the latest release, quoting:
Fix bug: potential crash on "Save as icon and close" for a model displayed in tabbed model viewer

Is this by any chance what you did / what was happening?

thanks

sven
