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

Dear all, I have to do a series of non linear least squares estimation within a loop and save the results in a matrix. 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? Thanks Giuseppe
