Fig. 1. Kolmogorov D values estimated for the different methods using data for the (A) Bygholm, (B) Maury, and (C) Karnak soils. LIN-2 = linear regression, two-parameter Weibull model; NLIN-2 = nonlinear regression, two-parameter Weibull model; ML-2 = maximum likelihood, two-parameter Weibull model; NLIN-3 = nonlinear regression, three-parameter Weibull model; ML-3 = maximum likelihood, three-parameter Weibull model. Bars indicate standard error of mean. Columns with the same letter within a soil are not significantly different at P < 0.05 according to t test.
