Thanks! But I could not find a corresponding example in the mentioned book - at least the calculation of the intra- and interrater variability or the corresponding intraclass coefficients. Karl

The key reference for this tool is: @Book{PB00:mixed, author = {J. C. Pinheiro and D. M. Bates}, title = {Mixed-effects models in S and Splus}, publisher = {Springer-Verlag}, year = 2000 } Cheers, Andrew On Tue, May 16, 2006 at 10:09:54AM +0000, Karl Knoblick wrote: > Hello! > > I want to calculate the intra- and interrater reliability of my study.
