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…
