ABSTRACT<\/strong><\/div>\n

Variable selection is fundamental to high-dimensional survival modeling. The regularized least squares method with appropriate penalty is a widely used method for simultaneous variable selection and coefficient estimation in linear regression, including accelerated failure time (AFT) model in survival analysis. I will discuss a variable selection technique which is based on a regularized weighted least squares method. Quadratic programming is used to solve this regularized weighted least squares objective function with\u00a0\"$\u00a0constraints and constraints that come due to the censored observations from the right censored data. This technique can be applied to survival data with\u00a0\"$\u00a0e.g. microarray data set. Simulation studies and real data example will be provided for illustration. In the beginning of this talk I will discuss the censoring effect on the Kaplan-Meier estimates when
\ndata are generated from different skewed failure time distributions.<\/p>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
