Is there anywhere to find more detail on the different types of predictions ("lp", "risk", "terms") in predict.coxph? I would like to create a summary risk score after fitting a multivariable model with time-varying covariates. If it makes a difference, 0 will be a substantively meaningful value for all of the covariates considered. -- Chuck Cleland, Ph.D. NDRI, Inc. 71 West 23rd Street, 8th floor New York, NY 10010 tel: (212) 845-4495 (Tu, Th) tel: (732) 452-1424 (M, W, F) fax: (917) 438-0894
