Detailed Description

Implements Beta random variate generators using the rejection method with log-logistic envelopes from [34] .

The method draws the first two uniforms from the main stream and uses the auxiliary stream for the remaining uniforms, when more than two are needed (i.e., when rejection occurs). The current implementation is adapted from UNURAN.

Constructor & Destructor Documentation

◆ BetaRejectionLoglogisticGen() [1/4]

BetaRejectionLoglogisticGen ( RandomStream  s,
RandomStream  aux,
double  alpha,
double  beta 
)

Creates a beta random variate generator with parameters \(\alpha=\) alpha and \(\beta=\) beta over the interval \((0,1)\), using main stream s and auxiliary stream aux.

The auxiliary stream is used when a random number of uniforms is required for a rejection-type generation method.

◆ BetaRejectionLoglogisticGen() [2/4]

BetaRejectionLoglogisticGen ( RandomStream  s,
RandomStream  aux,
double  alpha,
double  beta,
double  a,
double  b 
)

Creates a beta random variate generator with parameters \(\alpha=\) alpha and \(\beta=\) beta over the interval (a, b), using main stream s and auxiliary stream aux.

The auxiliary stream is used when a random number of uniforms is required for a rejection-type generation method.

◆ BetaRejectionLoglogisticGen() [3/4]

Creates a new generator for the distribution dist, using stream s and auxiliary stream aux.

The main stream is used for the first uniforms (before a rejection occurs) and the auxiliary stream is used afterwards (after the first rejection).

◆ BetaRejectionLoglogisticGen() [4/4]

Same as BetaRejectionLoglogisticGen(s, s, dist).

The auxiliary stream used will be the same as the main stream.
