public class BetaStratifiedRejectionGen
This class implements Beta random variate generators using the stratified rejection/patchwork rejection method. This method draws one uniform from the main stream and uses the auxiliary stream for any additional uniform variates that might be needed.
Constructor Summary | |
---|---|
BetaStratifiedRejectionGen(RandomStream s,
BetaDist dist)
Same as BetaStratifiedRejectionGen (s, s, dist). |
|
BetaStratifiedRejectionGen(RandomStream s,
double alpha,
double beta)
Creates a beta random variate generator with parameters α = alpha and β = beta, over the interval (0, 1), using stream s. |
|
BetaStratifiedRejectionGen(RandomStream s,
double alpha,
double beta,
double a,
double b)
Creates a beta random variate generator with parameters α = alpha and β = beta, over the interval (a, b), using stream s. |
|
BetaStratifiedRejectionGen(RandomStream s,
RandomStream aux,
BetaDist dist)
Creates a new generator for the distribution dist, using the given stream s and auxiliary stream aux. |
|
BetaStratifiedRejectionGen(RandomStream s,
RandomStream aux,
double alpha,
double beta)
Creates a beta random variate generator with parameters α = alpha and β = beta, over the interval (0, 1), using main stream s and auxiliary stream aux. |
|
BetaStratifiedRejectionGen(RandomStream s,
RandomStream aux,
double alpha,
double beta,
double a,
double b)
Creates a beta random variate generator with parameters α = alpha and β = beta, over the interval (a, b), using main stream s and auxiliary stream aux. |
