Fisher'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. The meta-analysis null hypothesis is … See more • Extensions of Fisher's method • An alternative source for Fisher's 1948 note: [1] See more WebDeveloped in 1874 [1] by Hermann Paasche, the formula: compares the total cost of a new basket of goods at the old and new prices.
