Changes in version 0.0.3 (2023-09-20)                  

  - CoxAIPW function now includes an additional crossFit parameter,
    which can be turned to FALSE to stop cross-fitting when all nuisance
    function estimators are root-n.

  - CoxAIPW function now includes an additional augmentation parameter
    in replacement of the previous 'random_censoring' parameter.
    Augmentation with respect to either propensity score, censoring or
    both can be selected.

  - Under non-proportional hazard model, CoxAIPW estimates a causal
    estimated that is a weighted average of the time-varying log hazard
    ratio. It also outputs x and y values for producing a smoothed plot
    of the time-varying log hazard ratio.

  - Update reference articles in the DESCRIPTION.

                 Changes in version 0.0.2 (2023-05-31)                  

  - CoxAIPW function now also outputs cumulative baseline hazard
    function and survival function for both groups, all of which
    evaluated at each follow up time.

  - CoxAIPW function now supports an additional 'random_censoring'
    parameter, which allows simplified estimation under the random
    censoring assumption instead of the informative censoring
    assumption.

  - CoxAIPW function now supports data with tied event times.

  - Update referenced articles in the DESCRIPTION.

                 Changes in version 0.0.1 (2023-02-08)                  

  - Added a NEWS.md file to track changes to the package.
