Introduction to Statistical Mediation Analysis

I'm using this book for Prof. MacKinnon's class, and the text is just as clear as he is in person (in fact, the text may be clearer in places).

This is THE book to read on mediation analysis. It should be titled "MacKinnon's Magical Methods for Managing Messy Mediational Models" because the boook is majorly magnificent.

This is by far one of the most readable and straightforward statistics books that I have purchased. The books begins with the basics and provides a great conceptual picture of mediation for those who may not be familiar with this type of analysis.
