WebJan 17, 2014 · I'm using the function multinom from the nnet package to run a multinomial logistic regression. In multinomial logistic regression, as I understand it, the coefficients are the changes in the log of the ratio of the probability of a response over the probability of the reference response (i.e., ln(P(i)/P(r))=B 1 +B 2 *X... where i is one response category, r … Web2. Likelihood, the inverse of probability. The most intuitive modeling algorithms rely on likelihood. In short, they pick the model that is most likely to have generated the data.; We use the term likely in everyday speech, but in science likelihood has a specific meaning that is closely related to probability. Probability describes the chance that a certain …
