PODS results for estimation of Ω under varying prior on Ψ and sorting method for the 18 taxon-pair configuration. Scatterplots of true versus estimated values of Ω for 100 PODS under different models of prior distribution on Ψ and applying different sorting strategies for the 18 taxon-pair data configuration. PODS were analyzed using reference tables composed of 3 × 10⁶ samples from the prior. The dashed line is the identity line, and the red line is a simple linear regression of estimated Ω onto true Ω. a) Dirichlet-process prior with sorted summary statistics. b) Dirichlet-process prior with unsorted summary statistics. c) Uniform prior with sorted summary statistics. d) Uniform prior with unsorted summary statistics
