This is weird because I could have chosen the exact opposite test ( μ > 0) and sampled results - and still get p = 0.0175. It's almost as if the Fisher test does not take the direction of the hypothesis into account. Can anyone explain this? Thanks device to backup macbookWebEmerson Global Emerson device to assist standingFisher's method combines extreme value probabilities from each test, commonly known as "p-values", into one test statistic (X ) using the formula $${\displaystyle X_{2k}^{2}\sim -2\sum _{i=1}^{k}\log(p_{i}),}$$ where pi is the p-value for the i hypothesis test. When the p-values tend to be small, the test … See more In statistics, Fisher's method, also known as Fisher's combined probability test, is a technique for data fusion or "meta-analysis" (analysis of analyses). It was developed by and named for Ronald Fisher. In its basic form, it is … See more In cases where the tests are not independent, the null distribution of X is more complicated. A common strategy is to approximate the null distribution with a scaled See more A closely related approach to Fisher's method is Stouffer's Z, based on Z-scores rather than p-values, allowing incorporation of study weights. It is named for the sociologist Samuel A. Stouffer. If we let Zi = Φ (1−pi), where Φ is the standard normal See more Dependence among statistical tests is generally positive, which means that the p-value of X is too small (anti-conservative) if the dependency is not taken into account. Thus, if Fisher's method for independent tests is applied in a dependent setting, … See more Fisher's method is typically applied to a collection of independent test statistics, usually from separate studies having the same null hypothesis.
