WebTo take into account the equality of A and B, you should use the Dirichlet-trinomial test which can be find here. The third approach is to use the Bayesian Sign test. If you set p=0.5 in the McNemar exact test, then it is equivalent to the Sign test. The Bayesian Sign test's implementation can be found here. I hope this helps. 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 …

WebJan 20, 2014 · The Model. Coming up with a Bayesian alternative for the binomial test is almost a no-brainer. The data is a count of the successes and failures in some task (where what is labeled success is an arbitrary choice most of the time). Given this impoverished data (no predictor variables and no dependency between trials) the distribution for the … 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). When the goal is to ascertain the presence or absence of an effect, we … See more The functional form of the model (i.e., the likelihood; Etz, 2024) is guided by the nature of the data and the research question. For instance, if interest centers on the association … See more For Bayesian parameter estimation, interest centers on the posterior distribution of the model parameters. The posterior distribution reflects the relative plausibility of the parameter values after prior knowledge has … See more Dependent on the goal of the analysis and the statistical model, different data preprocessing steps might be taken. For instance, if the statistical model assumes normally distributed … See more

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. gas heaters vent freeWebJan 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.
