WebFrom a Bayesian point of view, the posterior distribution (a probability distribution like those shown in figure 1, but which combines the chosen prior with the data) incorporates all information about the treatment effect after seeing the data,4 and as a result the average value for this distribution (ie, the posterior mean) is an unbiased ... WebMay 15, 2016 · One simple example of model averaging is when you are deciding the order of a polynomial model. y i = ∑ j = 0 k x i j β j + e i. So you don't know the betas and you also don't know the value of k. And e i ∼ N ( 0, σ 2). For fixed k you have a least squares problem - with a proper prior it is "regularized" least squares. clear drainage medical term from a wound
