WebApplication. The random parameter logit model is estimated by providing a rpar argument to mlogit.This argument is a named vector, the names being the random coefficients and the values the name of the law of distribution. WebI have little experience using -fracpoly- and I am seeking advice. I have a variable AGE and a variable CAGE which is the centered version of AGE and I want to find out whether in a binary logistic reg model I should model age as linear or noinlinear in the logit. When I estimate a fractional polynomial regression using AGE, the findings ...
