Web...the lognormal Johnson curves are then related to τ and the cumulants through the equations 1 − δ = (ln τ) 2 , γ = 1 2ln{τ(τ − 1)/κ2} ξ = ±κ1 − exp{(1/2δ − γ)/δ}, λ = ±1, where the ± is the sign of κ3 =-=[16]-=-. Values for the cumulants κr of θj,k Y j, c are necessary to solve for the Johnson curve parameters. WebThe advantage of this approach is that once a particular Johnson curve has been fit, the normal integral can be used to compute the expected percentage points under the respective curve. Methods for fitting Johnson curves, so as to approximate the first four moments of an empirical distribution, are described in detail in Hahn and Shapiro, 1967 ...
