CONCORDANCE ESTIMATION WITH CENSORED REGRESSION MODELS

by

Zhezhen Jin, Ph.D.
Department of Biostatistics
Columbia University


Abstract

The concordance can be used to assess discriminative and predictive accuracy in statistical models. Recently, there has been significant development for regression models for censored data. We will review various censored regression, namely, accelerated failure time models, linear transformation models and general transformation models. After that, we will present concordance estimation in these censored regression models and discuss its applications. The asymptotic properties of the proposed estimators will be derived and the some numerical studies will be presented.

This is joint work with Dr. XinhuaLiu and Dr. Wei-Yann Tsai.
