Figure 2From: Bayesian reference analysis for exponential power regression modelsFrequentist coverage, as a function of p , of 95% HPD credible intervals for p and σ based on the reference priors π r 1 (solid line), π r 2 (dashed line), π r 3 (long-dashed line) and the noninformative prior πU (dotted line). Sample sizes: n=30, 50 and 100. Horizontal line indicates the 95% nominal level.Back to article page
