New features

  • The Gaugler-Kim-Liao class of tests for right-censored data is now available (see ?logrank_test and ?logrank_weight).
  • The pvalue(), midpvalue() and pvalue_interval() methods for objects of class "NullDistribution" are now vectorized.

Bug fixes

  • Precision issue in the density function of approximative (Monte Carlo) null distributions. This also impacts mid-p-values and p-value intervals.
  • Precision issue in the support of approximative (Monte Carlo) null distributions.
  • Precision issue in the symmetric median scores transformation.
  • The weighted logrank transformation returned nonsense scores when supplied non-right-censored input; it now results in an error.
  • The maximally selected statistics transformation for ordered factors returned the wrong labels under some circumstances.

User-visible changes

  • The ties.method argument of logrank_trafo() no longer allows using "logrank" and "HL" to specify mid-ranks and the Hothorn-Lausen method, respectively.
  • Documentation updates.

Deprecated and defunct

  • Function surv_test() is now defunct.
  • Option method = "discrete" in pvalue() is now defunct.
  • The dperm(), pperm() and qperm() methods for objects of class "AsymptNullDistribution" are no longer needed and have been removed.
