Hello. I'm looking for information on model assessment using ROC in a mixed model environment accessible through R or SPLUS. I just found an article in the Journal of Statistical Software (Liu & Wu. 2003. Estimating the area under a receiver operating characteristic (ROC) curve for repeated measures design. www.jstatsoft.org/v08/i12/roc.pdf) giving details of new code for SAS. Does this exist in R? I didn't see any mention in my searches thru roc/mixed/glmm/glmmPQL/repeated/lme, etc... on the r-project site so thought I would take a stab at a general call for help. Thanks in advance, Meg. *************************************************************** Meg Krawchuk Department of Renewable Resources 7-51 General Services Building University of Alberta Edmonton, Alberta T6G 2H1 megk at ualberta.ca http://www.ualberta.ca/~megk/web_page.html
