alcohol

This data set contains subjects' age at the time of death, and alcohol drinking habits.
The data set includes 7990 subjects and 7610 events.

Estimates time varying regression effects under Cox type models in
survival data using classification and regression tree. The codes in this package were
originally written in S-Plus for the paper "Survival Analysis with Time-Varying Regression
Effects Using a Tree-Based Approach," by Xu, R. and Adak, S. (2002) <doi:10.1111/j.0006-341X.2002.00305.x>, Biometrics, 58: 305-315.
Development of this package was supported by NIH grants AG053983 and AG057707,
and by the UCSD Altman Translational Research Institute, NIH grant UL1TR001442.

The example data are from the Honolulu Heart Program/Honolulu Asia Aging Study (HHP/HAAS).
