rbs {bibs}

Simulating from Birnbaum-Saunders (BS) distribution.

Description

Simulating from BS distribution whose density function is given by

f_{{BS}}(t|\alpha,\beta)=\frac{0.5t +0.5 \beta}{\sqrt{2\pi}\alpha \sqrt{\beta}t^{\frac{3}{2}}} \exp\left\{-\frac{(t-\beta)^2}{2\alpha^2\beta t}\right\},

where t>0. The parameters of GBS distribution are \alpha>0 and \beta>0.

Usage

rbs(n, alpha, beta)

Arguments

n

Size of required realizations.

alpha

Parameter alpha.

beta

Parameter beta.

Value

A vector of n realizations from distribution.
