Cluster randomized trials with pretest and posttest measurement

This data set contains SPSS syntaxes and simulated and real data for a statistical paper that compares different methods for analyzing a cluster randomized trial with a pretest and a posttest of a quantitative outcome variable. There is also a pdf which states per other file its type (spss system file or syntax file) and its role in the project. Basically, there are three files (one system file, two syntaxes) for doing simulations, and nine files (three system files, six syntaxes) for analyzing real data from a published cluster randomized trial (Kraag et al., J Child Psychology and Psychiatry, 2009). The system files with real data have restricted access in view of EU privacy legislation. All other files are freely accessible.
