Bayesian binomial test

WebBackground. Let x = ( x 1, …, x n) be a set of success counts from a binomial distribution with unknown N and θ. Further, I assume that N follows a Poisson distribution with parameter μ (as discussed in the paper). Then, each x i has a Poisson distribution with mean λ = μ θ. I want to specify the priors in terms of λ and θ. In statistics, the binomial test is an exact test of the statistical significance of deviations from a theoretically expected distribution of observations into two categories using sample data.

The principled approach to Bayesian hypothesis testing is by means of the Bayes factor (e.g., Etz & Wagenmakers, 2024; Jeffreys, 1939; Ly, Verhagen, & Wagenmakers, 2016; Wrinch & Jeffreys, 1921). The Bayes factor quantifies the relative predictive performance of two rival hypotheses, and it is … See more We recommend that researchers carefully consider their goal, that is, the research question that they wish to answer, prior to the study (Jeffreys, 1939).

WebJan 14, 2024 · One of the features that we have recently added to JASP is a Bayesian “A/B test”, that is, a test for the equality of two binomial proportions. This test is especially popular in the analysis of clinical trial data, where the proportion of medical successes (or failures) from a treatment group is contrasted against those from a control group. WebBinomial probability is the relatively simple case of estimating the proportion of successes in a series of yes/no trials. The perennial example is estimating the proportion of heads in a series of coin flips where each trial is independent and has possibility of heads or tails. Because of its relative simplicity, the binomial case is a great place to start when …

WebTitle: Bayesian decomposable graphical models which are discrete and parametric. Abstract: Discrete graphical models are typically non-parametric with unknowns being cell probabilities in a multiway table. In contrast, continuous graphical models are Gaussian and thus fully parametric, which considerably reduces the number of unknowns.
