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 Webted using standard formula-based R interfaces. Functions for the estimation of potentially stratified Cox models, several survival regression models including log-normal or log-logistic models, models for ordered categorical responses (proportional odds, proportional hazards, probit) are available. how do you spell hula hoop
