beta_laplace

Evaluate the function beta for the Laplace prior

DESCRIPTION

Given a value or vector of values, find the value(s) of the function beta, defined as (g/phi - 1), where g is the marginal density conditional on the mean being nonzero and having a Laplace prior.

USAGE

beta_laplace(x, a)

REQUIRED ARGUMENTS

x	a data value or a vector of data

OPTIONAL ARGUMENTS

a	the scale parameter of the Laplace prior (default value = 1)

VALUE

A vector the same length as x is returned, containing the value(s) beta(x).
