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.

- Added
`conf.int`

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.

- Fixed bug

- Added average of t-years and percentiles
- Fixed median survival time (quantile)

- Added pbc sample data

- Initial release
