This category contains results about the Laplace distribution.
Let $X$ be a continuous random variable on a probability space $\struct {\Omega, \Sigma, \Pr}$.
Let $\Img X = \R$.
Let $\mu$ be a real number.
Let $b$ be a strictly positive real number.
$X$ is said to have a Laplace distribution with parameters $\mu$ and $b$ if and only if it has probability density function:
- $\map {f_X} x = \dfrac 1 {2 b} \map \exp {- \dfrac {\size {x - \mu} } b}$
This is written:
- $X \sim \map {\operatorname {Laplace} } {\mu, b}$
