Solution:

Customer may need to apply multinomial logistic regression for their analysis, but there is not currently a built-in function to handle this. The current alternative suggestions are:

(1) The multinom() function (by Prof. Brian D. Ripley), available in the nnet library, for the basic multinomial regression model. The nnet library is included with S+. To load this library, type the following at your S+ command prompt:

> library(nnet)

(2) The Design library (by Dr. Frank Harrell) for ordered multinomial regression models. This library is also included with S+. To load this library, type the following at your S+ command prompt:

> library(design)
