Bayes-optimal estimation of overlap between populations of fixed size

Fig 4

Credible intervals quantify uncertainty in overlap estimates.

By using Eq (8), 90% credible intervals are show above as error bars around the point estimates for varying true overlap s. As sampling rate increases from n_a = n_b = 30 (left) to 40 (middle) and to 50 (right), credible intervals shrink, indicating a reduction in uncertainty. In expectation, 90% of intervals cover the true overlap (dotted line).
