Fisher's method for combining p-values
WebOct 29, 2014 · We offer two statistical tests to combine p-values: selfcontained.test vs competitive.test. The goal is to test whether a vector of pvalues are jointly significant when we combine them together. Advantage 1: The Lancaster procedure is a generalized Fisher's method with weight functions to p-values. Advantage 2: Correlations among p … WebThe p-value combination method is an important strategy for testing the global hypothe-ses. Specifically, following the general setting in (1.1), we define the input p-values as Pi =1 −F0(Xi), i =1,...,n. The input p-values are combined to form a test statistic, and its test p-value is then obtained for testing the H0.
