Ultrahigh dimensional variable selection: beyond the linear model
Jianqing Fan, Richard Samworth, Yichao Wu
Variable selection in high-dimensional space characterizes many contemporary problems in scientific discovery and decision making. Many frequently-used techniques are based on inde…
Choice of neighbor order in nearest-neighbor classification
Peter Hall, Byeong U. Park, Richard J. Samworth
The th-nearest neighbor rule is arguably the simplest and most intuitively appealing nonparametric classification procedure. However, application of this method is inhibited by…
Maximum likelihood estimation of a multidimensional log-concave density
Madeleine Cule, Richard Samworth, Michael Stewart
Let X_1, ..., X_n be independent and identically distributed random vectors with a log-concave (Lebesgue) density f. We first prove that, with probability one, there exists a uniqu…
