WebBackground. Roughly, given a set of independent identically distributed data conditioned on an unknown parameter , a sufficient statistic is a function () whose value contains all the information needed to compute any estimate of the parameter (e.g. a maximum likelihood estimate). Due to the factorization theorem (), for a sufficient statistic (), the probability … WebSobre. • Ex-Diretor Presidente da Empresa Júnior, Fisher Consultoria Estatística da UFPE. • Sou Analista de BI na Traktor e atuo em modelagem e análise de Dados para negócios de clientes utilizando de técnicas de machine learning como modelos de classificação (XGBoost, Decision Tree, Gradient Boosting e etc), testes paramétricos e ... 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 χ -distribution random variable. Different approaches may be used depending on … 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 … 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 that all of the separate null hypotheses are true.
