In Gelman and Hill's 2007 book, Data Analysis Using Regression and Multilevel/Hierarchical Models, chapter 11 begins the exploration of multilevel models. To do so, they introduce a data set that relates city level child support enforcement policies to individual outcomes. Because the treatment is at the city level, this serves to show how sometimes it is good to model the city level effects (at the higher level of the hieratchical model) and then model those as having effects on individuals (the lower level). I'd like to follow along but the data set doesn't seem to be in either of the two places on Gelman's website where he keeps data:
- Data and software for the examples in the book
- More data and software for the examples in the book. (Sorry we're a bit disorganized right now!)
Anyone know where to find these data?
