Web9 feb. 2024 · The multinomial distribution is a generalization of the binomial distribution. As with all distribution functions in R, the first letter of the name indicates what is returned, … WebI ran a multinomial logit model in JMP and got back results which included the AIC as well chi-squared p-values for each parameter estimate. The model has one categorical outcome and 7 categorical explanatory vars. I then fit what I thought would build the same model in R, using the multinom function in the nnet package. The code was basically:
WebFrom a methodological perspective [12,31,32,33,34], the multinomial logit model is popular in the analysis of injury severity because it has a separate function for each injury severity level.
