Inference for Model-Free Between-Group Parameters for Censored Survival Data

Performs inference of several model-free group contrast measures, which include difference/ratio of cumulative incidence rates at given time points, quantiles, and restricted mean survival times (RMST). Two kinds of covariate adjustment procedures (i.e., regression and augmentation) for inference of the metrics based on RMST are also included.


surv2sampleComp 1.0-5

Minor improvements

  • Added argument in surv2sample(), rmstaug(), and rmstreg() to specify the confidence coefficient of confidence intervals.
  • Added tau_start argument in rmst2sample() to calculate the restricted mean survival time beyond a specific time point (to calculate AUC between tau_start and tau).
  • The integrated restricted mean survival time (Zhao et al., 2012) is now calculated in surv2sample().
  • No default value for the truncation time point, tau, in rmst2sample(). tau needs to be specified by users.
