11. Suppose we have a convergent MCMC algorithm for drawing samples from p(θ|y) ∝ f(y|θ)π(θ). We wish to locate potential outliers by computing the conditional predictive ordinate f(yi|y(i)) given in equation
(2.29) for each i = 1,...,n. Give a computational formula we could use to obtain a simulation-consistent estimate of f(yi|y(i)). What criterion might we use to classify yi as a suspected outlier?
