Probability Density Function of the 3-Parameter Log-Normal Distribution

Description

This function computes the probability density of the Log-Normal3 distribution given parameters (zeta, μ, and σ) of the distribution computed by parln3. The probability density function function of the distribution is

f(x) = frac{exp{kappa y - y^2/2}}{α sqrt{2π}} mbox{,}

where Phi is the cumulative ditribution function of the standard normal distribution and y is

Usage

pdfln3(x, para)

Arguments

x A real value.
para The parameters from parln3 or similar.

Value

Probability density (f) for x.
