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.
