The Statistics Seminar speaker for October 22nd, 2014 will be Jon Wellner from University of Washington.
Talk Title: Nonparametric Estimation of Log-Concave Densities
Abstract: I will review recent progress concerning nonparametric estimation of log-concave densities and related families in R1 and Rd. In the case of R1, I will present limit theory for the estimators at fixed points at which the population density has a non-zero second derivative and for the resulting natural mode estimator under a corresponding hypothesis. In the case of Rd with d ≥ 2 will briefly discuss some recent progress and sketch a variety of open problems.
Refreshments will be served after the seminar in 1181 Comstock Hall.
