Mixed and Multilevel Models Resources

Books

	SAS for Mixed Models, Second Edition by Ramon Littell, George Miliken, Walter Stroup, Russell Wolfinger, & Oliver Schabenberger This is a pretty technical book, and is not for the statistically feeble. But if you’re doing mixed models, you’re not statistically feeble. That said, if you are doing Mixed Modeling in SAS, it’s a must-have book. Back in the Cornell Statistical Consulting office, we actually wore out the book.
