Web26 set 2024 · 5. An HPD region is defined as. h τ = def { θ; π ( θ x) > τ } and it is an interval only when the parameter is unidimensional and the posterior is unimodal. Assuming this is the case and the posterior π ( ⋅ x) is available up to a multiplicative constant, finding an HPD interval consists in solving in θ the equation. π ( θ x) = τ.

Web1 giu 2024 · This counter example can be found in the reference. First notice that, if the density is unimodal, then the HPD is an interval. Moreover, except in extreme cases,the endpoints of the interval have the same density value. Suppose that x = ( x i) i = 1 n is a c.i.i.d. sample with x 1 θ ∼ e x p ( θ). Consider the prior θ ∼ G a ( a, b). Web1 giorno fa · Bayesian skyline analysis revealed that JEV GIa groups exhibited no significant growth during the past 40 years.
