public class LogarithmicGen
This class implements random variate generators for the (discrete) logarithmic distribution. Its mass function is
A local copy of the parameter θ is maintained in this class.
Constructor Summary | |
---|---|
LogarithmicGen(RandomStream s,
double theta)
Creates a logarithmic random variate generator with parameters θ = theta and default value θ0 = 0.96, using stream s. |
|
LogarithmicGen(RandomStream s,
double theta,
double theta0)
Creates a logarithmic random variate generator with parameters θ = theta and θ0 = |
|
LogarithmicGen(RandomStream s,
LogarithmicDist dist)
Creates a new generator with distribution dist and stream s, with default value θ0 = 0.96. |
|
LogarithmicGen(RandomStream s,
LogarithmicDist dist,
double theta0)
Creates a new generator with distribution dist and stream s, with θ0 = |
