RiskLaplace

Description

RiskLaplace specifies a Laplace distribution with location parameter and scale parameter . The Laplace distribution is sometimes called a “double exponential distribution” because it resembles two exponential distributions placed back to back around the location parameter.

 

Examples

RiskLaplace(10,20) returns a Laplace distribution with location parameter 10 and scale parameter 20.

RiskLaplace(A6,A7) returns a Laplace distribution with location parameter taken from cell A6 and scale parameter taken from cell A7.
