Summary

A log-Laplace continuous random variable.

Notes

The probability density function for loglaplace is:

f (x, c) = {\frac{c}{2} x^{c - 1} \frac{c}{2} x^{- c - 1} for 0 < x < 1 for x \geq 1

for $c > 0$ .

loglaplace takes c as a shape parameter for $c$ .

%(after_notes)s

Suppose a random variable X follows the Laplace distribution with location a and scale b. Then Y = exp(X) follows the log-Laplace distribution with c = 1 / b and scale = exp(a).
