Hi all, I am trying to extract the residuals from the following Weibull model.. The results I am getting are a bit strange. library(survival) mod=survreg(Surv(time, delta) ~ p1+p2+p3, data=testd, dist="weibull") ores=resid(mod, type='response') Are the commands correct? How do I get teh standardized residuals too? Thanks Val [[alternative HTML version deleted]]
