Subject: Packages micEcon, sampleSelection, and maxLik
Dear R Users:
We have splitted up the micEcon package into three packages:
a) Package "maxLik" provides tools for maximum likelihood estimations
(see http://www.maxLik.org).
b) Package "sampleSelection" provides tools for estimating Heckman-type sample
selection/generalized tobit models (see http://www.sampleSelection.org).
c) Package "micEcon" contains the remainder, i.e. mainly tools for
microeconomic demand and firm models, e.g. estimating the "Almost Ideal
Demand System" or the "Symmetric Normalized Quadratic" / "Symmetric
Generalized McFadden" profit function (see http://www.micEcon.org).
All these packages are available for download from CRAN and from their
websites (see above).
Any comments and suggestions on these packages are welcome!
Ott & Arne
