Hi List, Does anyone know if nlme or lme4 code is available for the examples in RB 2002 (specifically Chapter 8, but other chapters also if available). Thanks, Juliet
examples in Raudenbush and Bryk

It would not be difficult to code up those examples in lme or lmer if we could get access to the data sets. Are the data sets available, perhaps with the HLM software?

I found this: ftp://ftp.lisrel.com/hlm/unix/hlm5exs.tar.Z According to the readme ftp://ftp.lisrel.com/hlm/unix/readme the datasets accompany the HLM5 manual, but some (HSB1 from appendixa/ e.g.) are reported elsewhere as being analyzed in Raudenbush and Bryk (2002). I don't have a copy so cannot help in identifying the data from Chapter 8 (if present). HTH, Tobias

Thanks for checking on that, Tobias. As far as I can see that tar file contains the data from the High School and Beyond study (HSB) in appendix a, the EG data set in appendix b and the THAI data set in appendix c. These are the ones available in an ASCII format. Other data sets are only available in a SAS format for a VM/CMS machine (interesting concept of "portable data format"). One can convert these to R data sets. The EG data are already available as egsingle in the mlmRev package and a truncated version of the HSB data are available as Hsb82 in the same package. The THAI data can be converted as shown in the enclosed.
HTH, Tobias
