Note

This dataset is constructed from the raw data. There are a few differences with the data set used in Chapter 4 and 5 of Snijders and Bosker:

1. All schools are included, including the five school with missing values on langpost.

2. Missing denomina codes are left as missing.

3. Aggregates are undefined in the presence of missing data in the underlying values. Variables ses, iqv and iqp are in their original scale, and not globally centered. No aggregate variables at the school level are included.

4. There is a wider selection of original variables. Note however that the source data contain an even wider set of variables.
