RAND Statistics Seminar Series

Doing Thousands of Hypothesis Tests at the Same Time

Presented by Dr. Bradley Efron
Thursday, September 21, 2006
RAND Corporation, Santa Monica, CA
Please contact Stephanie Thomas if you would like to attend this seminar.


Classic multiple comparisons theory, beginning with the Bonferroni bound, was aimed at preserving frequentist p-values when simultaneously dealing with several testing problems. "Several" meant two to perhaps twenty. Modern scientific technology—microarrays being the prototype—routinely confront the statistician with thousands of simultaneous tests. Statistical inference can be qualitatively different in such situations, with Bayes or empirical Bayes ideas forcing themselves even upon dedicated frequentists. The emphasis will be more on examples and general guidelines than on theory.
