[R] variance components

2008-08-18 Thread John Sorkin
Please forgive the cross posting. I sent this to Medstats and have not received any response. I am looking for a good written explanation of components of variance (a.k.a variance components), in particular as they are used in genetic analyses. Does anyone have a suggestion? I am interested in

[R] variance components models with zero estimates

2008-06-07 Thread David Airey
When a variance components mixed model is run in Stata, if some of the variance components are zero, the model may not converge, for rational reasons. However, when the same model is run in SAS, the models with variance components that estimate to zero nonetheless converge. If I'm intereste
