Hi all,

 

I’m trying to follow the sub-sample restriction example in the help menu for the test statistic calculator for comparing 2 means. I select the same variable in both slots and specify the restrictions, but when I hit the enter key the mean, std. dev. & sample size boxes get cleared out. Am I missing something? This is on Widows, gretl 2024c-git.

 

Hi Peter, it works for me here with the latest snapshot, actually it's the first time I have done this. Did you put the restriction in parentheses as described? Did you hit enter while the variable selection box had the focus? I think this is also necessary.

So thanks for the reminder about the help text there - I would never have guessed from the interface that something like that was possible. I'm wondering whether perhaps the restriction formulation should get its own optional field to make it clearer.

cheers
