Fig. 9: Validation of mcmcDivE accuracy using six different birth-death preservation simulations.
From: Global diversity dynamics in the fossil record are regionally heterogeneous
Plots in the left column show an example of diversity trajectories for one simulation: the true diversity is indicated with the dashed line, green line and shaded areas represent the mcmcDivE estimates and 95% confidence intervals. Purple, orange and red lines show the range-through, raw diversity and squares-extrapolated trajectories, respectively. Blue lines and shaded areas show diversity from coverage-based rarefaction/SQS and 95% confidence intervals. Violin plots show the distributions (range, 1st and 3rd quartiles and median) of absolute percentage errors and coefficient of determination between true and estimated diversity calculated from 100 simulations in each setting. The scenarios (A–F) refer to different birth-death and preservation settings as described in Table S65. Source data are provided as a Source Data file.
