laplace#
Generates random numbers with Laplace distribution.
Description#
The laplace
class object is used in the
generate
function to provide random numbers with Laplace distribution with mean value (or average)
a
and scalefactor ( b
, β
), where \(a, \beta \in R ; \beta > 0\). The scalefactor value
determines the standard deviation as:
The probability density function is given by:
The cumulative distribution function is as follows:
