Re: [Gretl-users] Manage non convergent NLS in a loop

I have to do a series of non linear least squares estimation within

The problem is that, when it happens that for some set of the parameters
the NLS does not converge, instead of returning a null vector and going
on with the loop, the program stops.
Is there a way in gretl to tell the program not to stop? Something like
the command "try" in R?
Yes, use "catch":
catch nls ...
...
end nls
