PSIS.jl implements the Pareto smoothed importance sampling (PSIS) algorithm from Vehtari et al, 2021. Given a set of importance weights used in some estimator, PSIS both improves the reliability of the estimates by smoothing the importance weights and acts as a diagnostic of the reliability of the estimates.
