Fig. 3From: Validation of appropriate estimation criteria for the number of components for separating a polymodal grain-size distribution into lognormal distributionsHistograms of the difference between the estimated and the true number of components. Histograms of the difference between the number of components estimated as optimal (Ne) and the true number of components (Nt) (Ne−Nt) for each criterion and each true component number. Dark gray bars indicate cases when the true number of components was estimated (Ne = Nt). The red lines are the median valuesBack to article page
