In evaluations of breast cancer therapies, the patients quality of life is receiving more and more attention. It is desirable that a treatment not only prolongs the overall survival life, but also improves the quality of life QOL. Quality-adjusted lifetime QAL is a measure that combines both the quality and the quantity of a persons lifetime. The goal of my research is to study how to draw inference about QAL in the presence of censoring. For the grant period, I have studied the following problems 1 Estimating survival functions of QAL 2 Testing the equality of two survival functions of QAL. 3 Testing the equality of survival functions of QAL from three or more groups. 4 Developing regression methods for evaluating the effects of covariates on QAL. My research has resulted in a manuscript that has been submitted and invited talks at statistical conferences.
