WebMay 14, 2024 · There does not appear to be a large effect here. An independent-samples Bayesian t-test with a default two-sided Cauchy prior on effect size yields the following result: The results show that 95% of the posterior mass under H1 falls in the interval from -0.503 to 0.233, well inside the default Cauchy’s interquartile range (i.e., [−.707,+.707]). WebReliability analysis for medical test for covid-19 is performed using a Bayesian network. A Bayesian network (BN) is a probabilistic graphical model that represents knowledge about an uncertain domain where each node corresponds to a random variable and each edge represents the corresponding conditional probability .
