Graphical analysis of the bootstrap results: (a) relative frequency histogram for the number of pairwise allocations made upon first crossing the stopping boundary $(Q_{\max }=250)$ , (b) relative frequency histogram for the number of pairwise allocations made upon first crossing the stopping boundary $(Q_{\max }=125)$ , (c) empirical cumulative distribution functions for the number of pairwise allocations made upon first crossing the stopping boundary and (d) relative frequency histograms for posterior mean for $\mathbb{E}[\mathrm{incremental}\mathrm{net}\mathrm{monetary}\mathrm{benefit}]$ once follow-up has concluded.
