Bayes rule multivariate joint gaussian
WebIn Bayesian model comparison, the marginalized variables θ{\displaystyle \theta }are parameters for a particular type of model, and the remaining variable M{\displaystyle M}is the identity of the model itself. In this case, the marginalized likelihood is the probability of the data given the model type, not assuming any particular model parameters. Webhigh posterior probabilities. We then show that the multivariate regression coefficients can be recovered under certain compatibility conditions. Finally, we quantify the uncertainty for the regression coefficients with frequentist validity through a Bernstein-von Mises type theorem. The result leads to selection consistency for the Bayesian ...

GPR has several benefits, working well on small datasets and having the ability to provide uncertainty measurements on the predictions. Background
