Hypothesis testing for equality of proportions with 3 samples up with some sort of hypothesis test to test whether the ratio of accounts of type a, b and c is . Multiple testing: for every hypothesis, we want to separately test each null hypothesis while the latter might be more relevant in practice, the former leads to great insight and many methods used for the multiple testing problem can be related back to global hypothesis tests, so let’s look at some interesting results for the global test first. Neuropsychological datasets typically consist of multiple, partially overlapping measures, henceforth termed outcomesa given neuropsychological domain—for example, executive function—is composed of multiple interrelated subfunctions, and frequently all subfunction outcomes of interest are subject to hypothesis testing.
