public class ParetoGen
This class implements random variate generators for one of the Pareto distributions, with parameters α > 0 and β > 0. Its density function is
Constructor Summary | |
---|---|
ParetoGen(RandomStream s,
double alpha)
Creates a Pareto random variate generator with parameters α = alpha and β = 1, using stream s. |
|
ParetoGen(RandomStream s,
double alpha,
double beta)
Creates a Pareto random variate generator with parameters α = alpha and β = beta, using stream s. |
|
ParetoGen(RandomStream s,
ParetoDist dist)
Creates a new generator for the Pareto distribution dist and stream s. |
