Changes in version 0.3.0 (2025-09-29)                  

Major changes

  - Simplified the interface of functions cox_cure() and cox_cure_net()
    through helper functions cox_cure.control(), cox_cure.mstep(),
    cox_cure_net.penalty().

Minor changes

  - Avoid unnecessary internal data standardization to improve
    computation efficiency.

                 Changes in version 0.2.2 (2021-01-08)                  

New features

  - Added AIC to outputs of fitted Cox cure models.
  - Added a new argument named cv_nfolds to cox_cure_net() and
    cox_cure_net.fit() for model selection by cross-validation.
  - Added new arguments named surv_offset and cure_offset for optional
    offset terms in survival model component and incidence model
    component, respectively, to cox_cure(), cox_cure.fit(),
    cox_cure_net(), and cox_cure_net.fit(). One or more offset terms can
    be also specified via corresponding formula.

Bug fixes

  - Fixed issue caused by zeros in specified surv_l1_penalty_factor and
    cure_l1_penalty_factor for cox_cure_net() and cox_cure_net.fit().
    Thank Sy Han Chiou for reporting this issue.

                 Changes in version 0.2.1 (2019-12-18)                  

Minor changes

  - Moved C++ header files to inst/include/ so that they can be linked
    by other packages.
  - Added testing suite with help of the tinytest package.
  - Adjusted default maximum number of iterations in M-steps for
    possibly faster convergence in function cox_cure and cox_cure_net.

Bug fixes

  - Fixed weight indices in function cIndex.

                 Changes in version 0.2.0 (2019-08-03)                  

New features

  - Added function cox_cure for fitting regular Cox cure rate model and
    an extended Cox cure rate model for right-censored data with
    uncertain event status.
  - Added function cox_cure_net for fitting regularized Cox cure rate
    model for right-censored data with possible uncertain event status.
  - Added function cIndex for computing concordance index with possible
    weights.
  - Added function simData4cure for simulating survival data with
    possible uncertain event status.

                        Changes in version 0.1.0                        

Major changes

  - Added methods for parameters' initialization.

New features

  - Alpha version of the package for paper submission and ease of
    reproducing main simulation results.
