Re: [Gretl-devel] testcases and pet projects

I've checked the large number of mle, gmm and arma test scripts that I have to hand. In no case did the final maximized likelihood differ between the "bad d" and "good d" runs, to the digits we print. In some cases the parameter estimates differed, but only among the trailing digits that are anyway essentially random for numerical optimization problems (they change with compiler version/options and other environmental factors).

So, certainly this is a worthwhile fix, but people needn't worry about gretl producing bad MLE results for the last couple of years! We may have taken a few too many iterations -- or at worst, given a (rare) error when no error was called for.
