Figure 1.

Distribution of total variance σ² given $\widehat{\beta }$ (3.3); dashed curve counts from 25,000 parametric bootstrap replications (2.8), “Boot” row of Table 1; solid curve weighted counts (3.5), weights r_i = π(β_i)R(β_i), with π(β) the Jeffreys prior 1σ² and R(β) the conversion factor (2.15). Corrected bootstrap distribution “Bca” agrees with Jeffreys.
