Example 9.12: simpler ways to carry out permutation tests
In a previous entry, as well as section 2.4.3 of the book, we describe how to carry out a 2 group permutation test in SAS as well as with the coin package in R. We demonstrate with comparing the ages of the female and male subjects in the HELP study.I…

Example 9.10: more regression trees and recursive partitioning with "partykit"
We discuss recursive partitioning, a technique for classification and regression using a decision tree in section 6.7.3 of the book. Support for these methods is available within the rpart package. Torsten Hothorn and Achim Zeileis have extended the …

Example 8.24: MplusAutomation and Mplus
In recent entries (here, here, and here), we’ve been fitting a series of latent class models using SAS and R. One of the most commonly used and powerful software package for latent class model estimation is Mplus. This commercial software includes su…
