Hi, now that the regls addon is shipped with gretl and also covers the ridge estimator, I wonder (as a package author) what we should do with the ridge.gfn (or is it zip?) package. - AFAICS currently the main advantage of the package is that it runs with older gretl versions. (I haven't checked explicitly but I guess regls requires a very recent gretl version?) We could update its help text with a sentence like "we recommend to use regls unless your gretl version is older than xxxx", and then keep it around for a while. - Is there anything else which is in ridge but is missing in regls? thanks sven
