title: 'CoxAalenCR: Additive-Multiplicative Cox-Aalen Subdistribution Hazard Model
  for Competing Risks'
version: 0.1.0
doi: 10.32614/CRAN.package.CoxAalenCR
abstract: Implements the flexible additive-multiplicative Cox-Aalen subdistribution
  hazard regression model for competing risks data as proposed by Li and Long (2019)
  <https://doi.org/10.1007/s11424-019-7281-6>. The framework accommodates both time-varying
  non-parametric additive covariate effects through an Aalen (1980) additive model
  and constant multiplicative effects via a Cox proportional hazards structure, generalizing
  Scheike and Zhang (2002) <https://doi.org/10.1111/1467-9469.00065> and Martinussen
  and Scheike (2002) <https://doi.org/10.1093/biomet/89.2.283>. Includes inverse probability
  of censoring weighting (IPCW) with both Kaplan-Meier weights (Fine and Gray, 1999
  <https://doi.org/10.1080/01621459.1999.10474144>) and covariate-dependent Cox censoring
  weights (He et al., 2016 <https://doi.org/10.1111/sjos.12172>; Li and Long, 2019
  <https://doi.org/10.1007/s11424-019-7281-6>). Provides simultaneous estimating equations
  based on Huffer and McKeague (1991) <https://doi.org/10.1080/01621459.1991.10475010>,
  asymptotic sandwich variance estimation with censoring-weight martingale corrections,
  cumulative incidence function (CIF) prediction with pointwise confidence intervals,
  supremum-type goodness-of-fit tests for time-varying covariate effects, and Monte
  Carlo competing risks data simulation.
