The QUANTLIFE Procedure


The QUANTLIFE procedure provides the following features:

  • quantile regression methods for censored data that are based on generalizations of the Kaplan-Meier and the Nelson-Aalen estimator

  • the interior point algorithm for parameter estimation, which uses parallel computing when multiple processors are available

  • hypothesis tests for the regression parameter

  • semiparametric quantile regression that uses spline effects

  • survival plots, conditional quantile plots, and quantile process plots
