Applied Mathematics / Center for Statistical Sciences Seminar
Error controls for multiple hypothesis testing
Zhiyi Chi

Associate Professor
Department of Statistics
University of Connecticut

Multiple hypothesis testing is challenging when signals in data are weak, the distributions of noise and signals are not completely known, or there is statistical dependency in data.  I will present some theoretical results on these issues.  I will show that self-normalized large deviations can be useful in dealing with experiment designs for weak signals, linear programming can be used to evaluate p-values when data distributions are not completely known, and techniques similar to nonlinear filtering can be used to analyze the performance of multiple testing on hidden states of Markov models that may be nonstationary.
