WebKarl Fischer titration is used for many substances as a reference method, and is a chemical analysis based on the oxidation of sulfur dioxide by iodine in a methanolic hydroxide solution. In principle, the following … 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 used to combine the results from several independence tests bearing upon the same … See more 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 … 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 … See more Fisher's method is typically applied to a collection of independent test statistics, usually from separate studies having the same null … See more • Extensions of Fisher's method • An alternative source for Fisher's 1948 note: [1] • The Fisher's, Stouffer's Z-score, and a few related methods are implemented in the See more WebCopy the example data in the following table, and paste it in cell A1 of a new Excel worksheet.
