A minimum Wasserstein distance approach to Fisher's combination of independent discrete p-values
Gonzalo Contador, Zheyang Wu
This paper introduces a comprehensive framework to adjust a discrete test statistic for improving its hypothesis testing procedure. The adjustment minimizes the Wasserstein distanc…
An efficient and accurate approximation to the distribution of quadratic forms of Gaussian variables
Hong Zhang, Judong Shen, Zheyang Wu
In computational and applied statistics, it is of great interest to get fast and accurate calculation for the distributions of the quadratic forms of Gaussian random variables. Thi…
Accurate -Value Calculation for Generalized Fisher's Combination Tests Under Dependence
Hong Zhang, Zheyang Wu
Combining dependent tests of significance has broad applications but the -value calculation is challenging. Current moment-matching methods (e.g., Brown's approximation) for Fis…
Generalized Goodness-Of-Fit Tests for Correlated Data
Hong Zhang, Zheyang Wu
This paper concerns the problem of applying the generalized goodness-of-fit (gGOF) type tests for analyzing correlated data. The gGOF family broadly covers the maximum-based testin…
TFisher Tests: Optimal and Adaptive Thresholding for Combining -Values
Hong Zhang, Tiejun Tong, John E Landers +1
For testing a group of hypotheses, tremendous -value combination methods have been developed and widely applied since 1930's. Some methods (e.g., the minimal -value) are opti…
Concussion classification via deep learning using whole-brain white matter fiber strains
Yunliang Cai, Shaoju Wu, Wei Zhao +2
Developing an accurate and reliable injury predictor is central to the biomechanical studies of traumatic brain injury. State-of-the-art efforts continue to rely on empirical, scal…
Distributions and Statistical Power of Optimal Signal-Detection Methods In Finite Cases
Hong Zhang, Jiashun Jin, Zheyang Wu
In big data analysis for detecting rare and weak signals among features, some grouping-test methods such as Higher Criticism test (HC), Berk-Jones test (B-J), and -divergenc…
Detection boundary and Higher Criticism approach for rare and weak genetic effects
Zheyang Wu, Yiming Sun, Shiquan He +3
Genome-wide association studies (GWAS) have identified many genetic factors underlying complex human traits. However, these factors have explained only a small fraction of these tr…
