Hi everybody, here's a service announcement: A new version (0.7) of the margeff_el contributed function package can now be found on the package server. The package was invented by Oleh Komashko and makes it possible to calculate marginal effects and elasticities for a range of models. As always, access the contributed package repo from within gretl through File/Function packages/On Server. (Given the complexity of the internals it is likely that if the user input is not 100% correct, then this may result in failures of the package. It would be very useful if everybody could report those cases here on the list such that those input errors can be caught and more helpful error messages can be provided). cheers sven
