This website is for the distribution of robust estimation
software for R.
Currently available is multinomRob() which provides the hyperbolic tangent estimator for overdispersed
multinomial regression models of count data described in "Robust
Estimation and Outlier Detection for Overdispersed Multinomial Models
of Count Data," American Journal of Political Science 2004,
48 (April): 391-410. The package is also able to estimate
overdispersed grouped multinomial logistic and multivariate-t
logistic models.
The easiest way to install multinomRob (if you have
an active network connection) is to type, from either the Unix shell
or the GUI terminal (Windows, Mac):
