WebBayesian univariate linear regression is an approach to Linear Regression where the statistical analysis is undertaken within the context of Bayesian inference. One-way ANOVA The Bayesian One-Way ANOVA procedure produces a one-way analysis of variance for a quantitative dependent variable by a single factor (independent) variable. WebBayesian analysis of logistic regression models is straightforward using conventional methods of Markov chain Monte Carlo (MCMC). To proceed, we must address two issues. First, we need to specify prior distributions for all of the parameters. Customary priors for logistic regression parameters in the mean function are flat normal priors.
