beta

Generates beta distributed random values.

Description

Description

The beta class object is used in the generate function to provide random numbers with beta distribution that has shape parameters p and q, displacement a, and scale parameter (b, β), where p, q, a, and .

The probability density function is given by:

where B(p, q) is the complete beta function.

The cumulative distribution function is as follows:

    beta(): beta((RealType)1.0, (RealType)1.0, (RealType)(0.0),
                 (RealType)(1.0)){} explicit beta(RealType p,
                 RealType q, RealType a, RealType b);
