coxrt - Cox Regression for Right Truncated Data

The coxrt package fits Cox regression based on retrospectively ascertained time-to-event data. The method uses Inverse-Probability-Weighting (IPW) estimating equations with stabilized weights as described in Vakulenko-Lagun, Mandel, and Betensky, Inverse-Probability-Weighting Methods for Cox Regression with Right Truncated Data (under revision for Biometrics, 2019).

The coxrt package provides two functions: coxph.RT that assumes positivity and coxph.RT.a0 that allows for adjustment of estimation under violation of positivity.

The coxrt package can be installed by

devtools::install_github("Bella2001/coxrt")
