Fig. 4. Statistical analyses of the particle-size distribution models for all soils using the F statistic, the Cp statistic (Mallows, 1973), and the Akaike's information criterion (AIC). The number above bars indicates the number of soils for which a model can be accepted instead of the Fredlund model. Jaky = Jaky model, SL = simple lognormal model, ORL = offset-renormalized lognormal model, ONL = offset-nonrenormalized lognormal model, SC = Shiozawa and Campbell model, and Gom = Gompertz model.
