Accerated failure time with generalized estimating equation

The aftgee package implements recently developed inference procedures for the accelerated failure time (AFT) models with both the rank-based approach and the least squares approach.


Regression models for recurrent event data

reReg implements a collection of regression models for recurrent event process and failure time. The package is still under active development.


ROC-guided survival trees and forests

This package is working in progress.


Semiparametric estimating functions

Functions for fitting semiparametric regression models for panel count survival data.


Transformation model for left-truncated right-censored survival data

tranSurv implements methods for survival analysis under a dependent truncation and independent right censoring via a structural transformation method.


Permutation tests for general dependent truncation

permDep implements permutation approaches to test for quasi-independence in left-truncated right-censored survival data.
