Abstract
The purpose of this paper is to classify UIS data in order to identify their risk, reduce drug abuse, and to prevent high-risk in HIV behavior. A method for fitting proportional hazards models to censored survival data is described. Stratification is performed recursively. A tree-based method for censored survival data is developed, based on maximizing the difference in survival between groups of patients represented by nodes in a binary tree.
