WebMay 11, 2012 · 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. There are a number of ways to combine these independent, partial tests. The Fisher method is one of these, and is perhaps the most famous and most widely used. The test was presented in Fisher’s now ...
