rstable.posit {BMAmevt}

Positive alpha-stable distribution.

Description

Random variable generator

Usage

rstable.posit(alpha = 0.5)

Arguments

alpha

The parameter of the alpha-stable random variable

Details

An alpha-stable random variable S with index \alpha is defined by its Laplace transform E(exp(tS))) = exp(-t^\alpha). The algorithm used here is directly derived from Stephenson (2003).

Value

A realization of the alpha-stable random variable.
