Social and behavioral research is often about data with a hierarchical or multilevel structure. Multilevel modeling used to be only for specialists. However, in the past decade, multilevel analysis software has become available that is both powerful and relatively accessible for applied researchers. There are also several reviews and monographs, applications in different fields ranging from psychology and sociology to medicine, and a thriving Internet discussion list with 1400+ subscribers.
In 1996 I wrote a small book to introduce (graduate) students to multilevel analysis. This book, Applied Multilevel Analysis, is still available on the publications section of my homepage as a downloadable pdf-file. However, I consider it outdated, and if you need a quick (and free) introduction to multilevel analysis I suggest that you download the introductory chapter of my 2010 book. This is the second edition of Multilevel Analysis, Techniques and Applications, published by Routledge.
For more information you can go to the general Routledge site, or you can go directly to the specific information about my book here. I plan to use this section of my homepage to put other book-related material, such as the example data sets. The example data are described in Appendix A of the book. In due time, I plan to add software setups and powerpoint files.
