[Gretl-devel] need for advise on a new package

Dear all, I want to do further development to existing series of mfx packages. Namely, I am going to add the following functionality: (ALL with standard errors) computing 4 statistics: me's, (+2 semi) elasticities (where correct) average marginal effects functions of independent variables with minimizing of use of numerical derivatives correct treatment of group dummies, corresponding to multi-level factor x's correct treatment of dummy-continuous and dummy-dummy interactions inclusion of "unmfx-ed" models, i.e. heckit  This is rather work-consuming. So, I'd like to proceed as following: submit a v.01 on probit only for testing: there are some questions about interface, and some others. I'd like to have wishes, suggestions, critic etc. before doing the rest. Currently I can compute AME, treat functions of continuous variables and group dummies (without interactions) I will appreciate your opinion. Oleh
