While earning my master’s degree in Human Development and Family Science at Ohio State University, I learned about hierarchical linear modeling (HLM). It sounded so cool. But I never had a chance to learn how to do it….until now.
It was a bit difficult for myself, as well as others (I had to ask around if I was the only one) to understand everything that was being taught, mainly because we were taught more about the formulas and why we should use them rather than focusing more attention to real-life examples and how we could organize our data and run actual model, for instance.
Thankfully, he wrote a book entitled Multilevel Analysis: Techniques and Applications (Second edition) that’s quite helpful at explaining how to do the analyses and he has a website (http://www.joophox.net/) with papers and programs so people can learn and practice more.
