SAGE/Biostatistics Seminar

Submitted by jlongwor on Thu, 10/21/2010 - 9:00am.

Survival Analysis Group Enhancement (SAGE) is a new series of talks aimed at enhancing a general education for people with interests in survival analysis.  Since Winter 2011, this has been conducted jointly with the Biostatistics Seminar Series, and is now known as the SAGE/Biostatistics Seminar.

In this talk, we will present a systematic analysis for the sample size calculation in high-dimensional classification analysis. We illustrate our new methods via a study design that uses proteomics markers to classify post-kidney transplantation patients into stable and rejection classes.
