Statistically Efficient Thinning of a Markov Chain Sampler by Owen, Art B.

“…It is common to subsample Markov chain output to reduce the storage burden. Geyer shows that discarding k − 1 out of every k observations will not improve…”

CONFOUNDER ADJUSTMENT IN MULTIPLE HYPOTHESIS TESTING by Wang, Jingshu, Zhao, Qingyuan, Hastie, Trevor, Owen, Art B.

“…We consider large-scale studies in which thousands of significance tests are performed simultaneously. In some of these studies, the multiple testing procedure…”

Bi-Cross-Validation for Factor Analysis by Owen, Art B., Wang, Jingshu

“…Factor analysis is over a century old, but it is still problematic to choose the number of factors for a given data set. We provide a systematic review of…”

Backfitting for large scale crossed random effects regressions by Ghosh, Swarnadip, Hastie, Trevor, Owen, Art B.

“…Regression models with crossed random effect errors can be very expensive to compute. The cost of both generalized least squares and Gibbs sampling can easily…”

KARL PEARSON'S META-ANALYSIS REVISITED by Owen, Art B.

“…This paper revisits a meta-analysis method proposed by Pearson [Biometrika 26 (1934) 425–442] and first used by David [Biometrika 26 (1934) 1–11]. It was…”

Extensible grids: uniform sampling on a space filling curve by He, Zhijian, Owen, Art B.

“…We study the properties of points in [0, 1]d generated by applying Hilbert's space filling curve to uniformly distributed points in [0, 1]. For deterministic…”

A general characterization of optimal tie-breaker designs by Li, Harrison H., Owen, Art B.

“…Tie-breaker designs trade off a measure of statistical efficiency against a short-term gain from preferentially assigning a binary treatment to subjects with…”

Comment: Unreasonable Effectiveness of Monte Carlo by Owen, Art B.

“…There is a role for statistical computation in numerical integration. However, the competition from incumbent methods looks to be stiffer for this problem than…”

Aging mice show a decreasing correlation of gene expression within genetic modules by Southworth, Lucinda K, Owen, Art B, Kim, Stuart K

“…In this work we present a method for the differential analysis of gene co-expression networks and apply this method to look for large-scale transcriptional…”
