WebSep 7, 2014 · In my previous post I wrote about the importance of age and why it is a good idea to try avoiding modeling it as a linear variable. In this post I will go through multiple options for (1) modeling non-linear effects in a linear regression setting, (2) benchmark the methods on a real dataset, and (3) look at how the non-linearities actually look. The post … WebAll macros assume that predicted probabilities have been saved for each model of interest, such as through logistic regression or some other method. Note that the predicted probabilities can be from any type of model and do not need to be nested. The bootstrap program that adjusts for optimism is the only exception since it compares nested models.
