boa.hpd {boa}

Highest Probability Density Interval

Description

Estimates the highest probability density (HPD) interval for the given parameter draws. Uses the Chen and Shao algorithm assuming a unimodal marginal posterior distribution.

Usage

boa.hpd(x, alpha)

Arguments

x

MCMC draws from the marginal posterior to use in computing the HPD.

alpha

Specifies the 100*(1 - alpha)% interal to compute.

Value

A vector containing the lower and upper bound of the HPD interval, labeled "Lower Bound" and "Upper Bound", respectively.
