We would like to announce the availability on CRAN of a new package
multinomRob. It does robust estimation of overdispersed multinomial
regression models. The package is also able to estimate overdispersed
grouped multinomial logistic and multivariate-t logistic models. The
code is relatively general; for example, it allows for equality
constraints across parameters and it can handle datasets in which the
number of categories varies by observation.
