Fisher's combined test

Web4.5 - Fisher's Exact Test. The tests discussed so far that use the chi-square approximation, including the Pearson and LRT for nominal data as well as the Mantel-Haenszel test for ordinal data, perform well when the contingency tables have a reasonable number of observations in each cell, as already discussed in Lesson 1. WebApr 6, 2024 · Among all tests, Fisher’s combined test is the most popular one and is routinely used in applications. In this article, we propose an alternative method of combining the p-values of independent tests using chi-square scores, referred to as the inverse chi-square test. The proposed test is as simple as other existing tests.

WebApr 9, 2007 · We propose using Fisher's combined p method to combine probe level tests of differential expression. Using three spike-in datasets and array data from a biological study, we compare the combined p method to the ANOVA method [ 8 ], Cyber-T [ 6 ], median t method [ 10 ], moderated t-test [ 4 ] and the original t-test.
