Dear Arne and Ott-Simm It always seemed weird to me mixing demand and firm models with SSel. models on a single package.
Separating them would seem the logical thing to do. On the other hand, one more R package :/ , I´m not too big of a fan of increasing this list ad infinitum. My take on this is that it would be worth it to split it if you think you´ll keep expanding the SSel. models under the new package. Otherwise keep it the way it is. I still dream of contributing a package that offers a group of SSel. models under a wide variety of settings, but still haven´t found the time to do so, nor it seems i´ll have it in the near future. On the other hand, judging by the low number of replies it seems to me that the audiece for SSel. in R is still quite limited. My two cents, greetings robert On 10/30/07, Arne Henningsen <[EMAIL PROTECTED]> wrote: > Dear R Users: > > The functions of our "micEcon" package [1,2] can be subdivided into three > categories: > - microeconomic demand and firm models > - sample selection models (mainly selection()) > - routines for (likelihood) maximisation (e.g. maxLik(), maxNR(), maxBHHH()) > (mainly used for ML estimation of sample selection models) > > Although sample selection models are often used in microeconomic analyses, > they are also used in several other disciplines.
