WebFeb 4, 2024 · predictions are rich, allowing for direct estimation of the hazard, survival, hazard ratios, hazard differences and survival differences. The models allow for time-varying effects, left truncation and relative survival. The R implementation departs from the Stata implementation, using the ns() function, which is Webas stated in Using Time Dependent Covariates and Time Dependent Coefficients in the Cox Model vignette in version 2.41-3 of the R survival package. Instead, you should use the time-transform functionality, i.e., the tt function as stated in the same vignette. The code would be something similar to the example in the vignette
