Dears, Unfortunatelly, the packages relaimpo and relimp do not seem to work with plm function (plm package) or gls function (in nlm package). I've been studying on how to adapt one of them for this pourpose. In that sense, I have two questions regarding to this work: 1) have anyone hard of any workaround for those incompatibilities, or at least of any ideas on that - especially for plm? 2) actually, it would make theoretical sense to adapt those packages for plm or gls? It seems to me that it would for plm, but not necessarily for gls due to the likelihood framework it works on. Anyone? Thanks in advance! Richard A. [[alternative HTML version deleted]]
