Global testing against sparse alternatives in time-frequency analysis
T. Tony Cai, Yonina C. Eldar, Xiaodong Li
In this paper, an over-sampled periodogram higher criticism (OPHC) test is proposed for the global detection of sparse periodic effects in a complex-valued time series. An explicit…
Inference for High-dimensional Differential Correlation Matrices
T. Tony Cai, Anru Zhang
Motivated by differential co-expression analysis in genomics, we consider in this paper estimation and testing of high-dimensional differential correlation matrices. An adaptive th…
Rate-Optimal Detection of Very Short Signal Segments
T. Tony Cai, Ming Yuan
Motivated by a range of applications in engineering and genomics, we consider in this paper detection of very short signal segments in three settings: signals with known shape, arb…
Discussion: "A significance test for the lasso"
T. Tony Cai, Ming Yuan
Discussion of "A significance test for the lasso" by Richard Lockhart, Jonathan Taylor, Ryan J. Tibshirani, Robert Tibshirani [arXiv:1301.7161].
Geometric Inference for General High-Dimensional Linear Inverse Problems
T. Tony Cai, Tengyuan Liang, Alexander Rakhlin
This paper presents a unified geometric framework for the statistical analysis of a general ill-posed linear inverse model which includes as special cases noisy compressed sensing,…
