Fisher's exact method
WebMay 11, 2012 · The logic of the Fisher method to combine P-values. Consider a set of independent tests, each of these to test a certain null hypothesis , . For each test, a significance level , i.e., a p-value, is obtained. All these p-values can be combined into a joint test whether there is a global effect, i.e., if a global null hypothesis can be rejected.
