A grouped, selectively weighted false discovery rate procedure
Xiongzhi Chen, Sanat K. Sarkar
False discovery rate (FDR) control in structured hypotheses testing is an important topic in simultaneous inference. Most existing methods that aim to utilize group structure among…
On Benjamini-Hochberg procedure applied to mid p-values
Xiongzhi Chen, Sanat K. Sarkar
Multiple testing with discrete p-values routinely arises in various scientific endeavors. However, procedures, including the false discovery rate (FDR) controlling Benjamini-Hochbe…
False discovery rate control for multiple testing based on p-values with càdlàg distribution functions
Xiongzhi Chen
For multiple testing based on p-values with càdlàg distribution functions, we propose an FDR procedure "BH+" with proven conservativeness. BH+ is at least as powerful as the BH pro…
Explicit solutions to a vector time series model and its induced model for business cycles
Xiongzhi Chen
This article gives the explicit solution to a general vector time series model that describes interacting, heterogeneous agents that operate under uncertainties but according to Ke…
A weighted FDR procedure under discrete and heterogeneous null distributions
Xiongzhi Chen, R. W. Doerge, Sanat K. Sarkar
Multiple testing with false discovery rate (FDR) control has been widely conducted in the ``discrete paradigm" where p-values have discrete and heterogeneous null distributions. Ho…
Consistent estimation of the proportion of false nulls and FDR for adaptive multiple testing Normal means under weak dependence
Xiongzhi Chen
We consider multiple testing means of many dependent Normal random variables that do not necessarily follow a joint Normal distribution. Under weak dependence, we show the uniform…
Multiple testing with discrete data: proportion of true null hypotheses and two adaptive FDR procedures
Xiongzhi Chen, Rebecca W. Doerge, Joseph F. Heyse
We consider multiple testing with false discovery rate (FDR) control when p-values have discrete and heterogeneous null distributions. We propose a new estimator of the proportion…
