In particular, I will describe the signal sizes necessary and sufficient for statistical procedures to simultaneously control false discovery (in terms of family-wise error rate or false discovery rate) and missed detection (in terms of family-wise non-discovery rate or false non-discovery rate) in the simple but ubiquitous signal-plus-noise model
x(i) = \mu(i) + \epsilon(i), \quad i=1,2,\ldots,p
Several well-known procedures are shown to attain said boundaries. Remarkably, these phase transition phenomena continue to hold under a much wider class of models, and under extremely weak dependence assumptions. We provide point-wise, rather than minimax, results, wherever we can. Important practical implications, along with an interesting manifestation of the phase transitions in genome-wide association studies (GWAS), will be discussed.
Behind the statistical results is a probabilistic phenomenon known as relative stability. Much like how the law of large numbers describes the concentration of averages, relative stability --- or the ""law of large dimensions"" --- describes the concentration of maxima. We provide a complete characterization of the relative stability phenomenon for Gaussian triangular arrays in terms of their correlation structure. Its proof uses classic Sudakov-Fernique and Slepian lemma arguments along with a curious application of Ramsey's coloring theorem.",https://events.umich.edu/event/69697,"West Hall",411,"West Hall",,seminar,"Department of Statistics"
