Single-index modulated multiple testing
Lilun Du, Chunming Zhang
In the context of large-scale multiple testing, hypotheses are often accompanied with certain prior information. In this paper, we present a single-index modulated (SIM) multiple t…
Multiple testing via for large-scale imaging data
Chunming Zhang, Jianqing Fan, Tao Yu
The multiple testing procedure plays an important role in detecting the presence of spatial signals for large-scale imaging data. Typically, the spatial signals are sparse but clus…
Semiparametric detection of significant activation for brain fMRI
Chunming Zhang, Tao Yu
Functional magnetic resonance imaging (fMRI) aims to locate activated regions in human brains when specific tasks are performed. The conventional tool for analyzing fMRI data appli…
Assessing prediction error of nonparametric regression and classification under Bregman divergence
Jianqing Fan, Chunming Zhang
Prediction error is critical to assessing the performance of statistical methods and selecting statistical models. We propose the cross-validation and approximated cross-validation…
Bump hunting with non-Gaussian kernels
Peter Hall, Michael C. Minnotte, Chunming Zhang
It is well known that the number of modes of a kernel density estimator is monotone nonincreasing in the bandwidth if the kernel is a Gaussian density. There is numerical evidence…
