Description

The hyperbolic-logarithm probability weighting function is given by

w(p) = (1 - alpha * log(p))^(-beta/alpha)

where p is the probability constrained by

w(0) = 0, w(1) = 1, 0 < p < 1,

and the two parameters alpha and beta are constrained by

alpha > 0, beta > 0.

Usage

Arguments

par

vector, contains the alpha and beta parameters for the pwf

p
