Hedeker, Donald. (2014, April 15). Cross-Classified and Multi-membership Multilevel Models. Institute for Health Research and Policy, University of Illinois at Chicago.

Cross-classified multilevel models apply when, say, a student is clustered within both a grammar and high school, but not all students from a given grammar school go the same high school. In this situation, the two types of clusters — grammar schools and high schools — do not represent hierarchical factors, but crossed factors. Multi-membership models are used in studies in which, for example, an individual patient may see multiple health care providers, or when a person is observed in multiple neighborhoods. In... more

Kim, Yoonsang. (2014, Jan. 14).  What You Need to Know about Proportions and Rates as Dependent Variables. Institute for Health Research and Policy, University of Illinois at Chicago.

What would you do when the variable of interest is continuous and restricted to the interval (0,1)? A linear regression assuming normality may not work because of the restricted range. Regression models for proportions and rates include beta regression and fractional logit regression. This Chalk Talk introduced these two approaches and reviewed their estimation methods, interpretation of parameters, and related statistical software.

Pugach, Oksana. (2013, Nov. 12). What You Need to Know about CART, Classification and Regression Trees [PDF of Word document]. Institute for Health Research and Policy, University of Illinois at Chicago.

Classification and regression trees are machine-learning methods for constructing prediction models from data. The models are obtained by recursively partitioning the data space and fitting a simple prediction model within each partition. As a result, the partitioning can be represented graphically as a decision tree.
