Webb14 nov. 2024 · Estimating power using the multinomial model can happen via two ways: By using PROC GLIMMIX + non-profiling to request ad-hoc power analysis. By simulating the multinomial data and then using PROC GLIMMIX — most flexible way. Now, lets see how to repeat the above examples by using the multinomial distribution and the cumulative logit … WebbThis is an assumption in logistic regression. If this does not hold you might want to consider adding higher order terms to the model, or even a nonlinear relationship between log odds of cancer and some of the variables (by fitting a generalized additive model).
