Vector of n Laplace distributed random numbers |
The vRngLaplace function generates random numbers with Laplace distribution with mean value (or average) a and scalefactor β, where a, β∈R ; β > 0. The scalefactor value determines the standard deviation as
The probability density function is given by:
The cumulative distribution function is as follows:
