Dear all, I am interested to evaluate reclassification using net reclassification improvement and Integrated Discrimination Index IDI after survival analysis (Cox proportional hazards using stcox). I search a R package or a R code that specifically addresses the categorical NRI for time-to-event data in the presence of censored observation and, if possible, at different follow-up time points. I know that the PredictABEL Package contains functions for NRI and IDI calculation but it is unclear for me if it allows censored observation. Package survIDINRI calculates only continuous NRI and the function of Package Hmisc[#rcorrp.cens(x1, x2, y) ##] is only for no censored observations.
Many thanks. Sincerely, Mario Petretta Dpt.
