Statitcal methos for the analysis of multi-way contigency tables

What is it about?

This paper explains how to analyze multi-way contingency tables using the R-package confreq (Heine, 2015). With confreq one may run log-linear models and also configural frequency analyses (CFA; von Eye, 2002) . Both statistical methods are very useful for analyzing categorical data; the may be applied even for small samples. The paper explains hwo to use the R package, by leading the reader through the R-syntax. Several methods of configural frequency analysis are presented. Advantages as well as limitations of CFA are explained.
