95% posterior credible intervals for μ for all simulated models where x̄₀ = 0, n₀ = 60, n = 30, and ${\widehat{\sigma }}_0^2=1$. Each graph contains results from eight different models: historical (top), full borrowing (second), MPP (third), Cauchy (fourth), LCPP (fifth), LCP (sixth), LSCMP (seventh), and no borrowing (bottom). Columns correspond to the current sample mean, x̄, while the top row shows results for σ̂² = 1 and the bottom row assumes σ̂² = 3.
