The TIMSS2007 database http://timss.bc.edu/TIMSS2007/idb_ug.html seems to provide "both kinds" of universal data formats - either SPSS saved data sets or SAS saved data sets. (Yes, I am being sarcastic.) These, of course, are accompanied by massive codebooks explaining the nature of each of the fields in the data sets. The T07_Codebooks.zip file available at that site contains .pdf files and .sdb files, which seem to contain the information from the codebooks in some kind of binary format. Does anyone know where that format is defined. I imagine I could reverse-engineer it but would prefer not to do so.
I would like to use part of this dataset as an example of a very large hierarchically structured data set for analysis in lme4. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
