Fig. 1. — Boxplots of RMSE ratios (-axis, on the log-scale) comparing four adaptive priors that make use of the historical information against a standard hierarchical shrinkage prior, plotted against varying sample sizes of the historical data (; -axis) for ten true values of the regression coefficients (, ; columns) taken from Table 2 and varying sample sizes of the current data (; rows). Each boxplot compares the posteriors across 128 independent datasets. Smaller ratios indicate better performance of the corresponding adaptive prior.
