Bayes’ theorem

a theorem stating the probability of an event occurring if another event has occurred. Bayesian statistics is concerned with the revision of opinion in the light of new information, i.e. hypotheses are set up, tested, and revised in the light of the data collected. On each successive occasion there emerges a different probability of the hypothesis being correct – ‘prior opinions are changed by data, through the operation of Bayes’ theorem, to yield posterior opinions’ (Phillips, 1973).

Considering as null hypothesis that mapping of the crude rate does not clearly identify the formation of agglomerates of deaths, and that the Empirical Bayesian analysis provides a re-configuration of the distribution of mortality and formation of agglomerates, the aim of this study was to compare the results obtained between the estimate by the crude rate and the Bayesian method for the rate of deaths from oral and oropharynx cancer, in the State of Minas Gerais, in 2012.

In order to apply Bayesian analysis to fMRI data and make inference to the parameters that we are interested in, like finding the change points in the dataset, we need to set up a probability model for the data and find a prior to apply Bayes' Rule.
The periconceptional use of some selective serotonin reuptake inhibitors (SSRIs) appears to have no impact on the development of birth defects, but some birth defects occur more frequently among infants of women treated with paroxetine or fluoxetine early in pregnancy, results from a Bayesian analysis demonstrated.
