...tential multiplicity of measurements per individual, treating each as independent. For example: id <- c(a,a,a,b,b,b) # patient id risenumber <- c(1,2,3,1,2,3) # number of each rise per patient clinfail <- c(1,1,1,0,0,0) # censored indicator of clinical failure status (the endpoint) clinfailtime <- c(5,4,3,10,9,8) # time from rise to clinical failure endpoint riseval <- c(10,20,30,1,2,3) # value of test at the time of rise timesinceRx <- c(1,2,3,1,2,3) # years since treatment Rxtype <- c(c,c,c,d,d,d) # type of treatment ...plus other variables at time of rise plus pre-trea...
