Behavior of the estimated PVP in different sample sizes. PVP values (y axis) against intracorrelations (x axis) for the simulated data. Simulations were run with 85 observations (A), 1000 observations (B), and 5000 observations (C). The star represents the true cluster, the cross represents the grouped singletons, and the rest of the markers represent other singleton clusters recovered as false positives (and therefore low PVP values).
