# Using {rms} package for multinomial logit

Is it possible to use the rms package to model multinomials logits, or elsewise to model several binary logits to achieve the same effect? I am aware that there are many other packages specifically designed to fit multinomial logits, but I am quite attached to the suite in rms.

• Not the answer you're looking for, but the multinom function in the nnet is superb. Uses the exact same functionality as any glm object (which technically speaking, it is). Aside from preference, what do you need form rms? – AdamO Jul 28 '15 at 19:13
• Bootstrapped covariance, prediction plots (with prediction intervals), influence statistics, and splines are some of the advantages I'm after. I'm actually using nnet and I don't have any issues with it—I think it covers my basic needs very well. – Johan Larsson Jul 28 '15 at 19:18
