Does anyone know of code to conduct hierarchical (that is, multi-level) models using R. Beyond simply requiring a nested design, I want to model explicitly the covariance between levels as is done in such multi-level modeling software as HLM or MLwin and discussed in Goldestein (1999) available online at http://www.arnoldpublishers.com/support/goldstein.htm (a nice and free resource for anyone interested in HLM). The work that I will be doing in the immediate future would involve linear applications of multi-level modeling, however I would be interested in code to conduct generalized hierarchichal models if it is available. I searched all of the archives available on CRAN and also the help list archives but turned nothing up. No, I take that back, I think I did find code for logistic multilevel models, but not linear.

There is code in Jim Lindsey's 'repeated' package (his page is linked from CRAN) for generalised linear models with random intercepts, but not, I think, for more general hierarchical structures. -thomas Thomas Lumley Assistant Professor, Biostatistics University of Washington, Seattle -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
