Robustness of the different fitting methods to variation in sample size (ranging from 50 to 1500 propagules). Fitting results correspond to the lognormal distribution. a Estimated parameter values (mean ± se). The solid and dashed lines indicate the original values of the location (μ) and variance (σ) parameters, respectively. Where error bars are undistinguishable, it means that standard errors are smaller than the mean-value dots. b KS statistic. c Fitting performance of the CD-ML method for different sample sizes, estimated by the KS statistic
