public class WeibullGen
This class implements random variate generators for the Weibull distribution. Its density is
The (non-static) nextDouble method simply calls inverseF on the distribution.
Constructor Summary | |
---|---|
WeibullGen(RandomStream s,
double alpha)
Creates a Weibull random variate generator with parameters α = alpha, λ = 1 and δ = 0, using stream s. |
|
WeibullGen(RandomStream s,
double alpha,
double lambda,
double delta)
Creates a Weibull random variate generator with parameters α = alpha, λ = lambda and δ = delta, using stream s. |
|
WeibullGen(RandomStream s,
WeibullDist dist)
Creates a new generator for the Weibull distribution dist and stream s. |
Method Summary | |
---|---|
double |
getAlpha()
Returns the parameter α. |
double |
getDelta()
Returns the parameter δ. |
double |
getLambda()
Returns the parameter λ. |
static double |
nextDouble(RandomStream s,
double alpha,
double lambda,
double delta)
Uses inversion to generate a new variate from the Weibull distribution with parameters α = alpha, λ = lambda, and δ = delta, using stream s. |
void |
setParams(double alpha,
double lambda,
double delta)
Sets the parameters α, λ and δ for this object. |
