One might think of these as ways of applying multinomial logistic regression when strata or clusters are apparent in the data.
It is used in the likelihood ratio chi square test of whether all predictors regression coefficients in the model are simultaneously zero and in tests of nested models. Log likelihood 179 98173 iteration 4. Once you have done that the calculation of the probabilities is straightforward. If the data are grouped thenniis the total number of trials in theith row of the dataset andyijis the number of trials in which outcomejoccurred.
