MathRandomNoncentralBeta

Generates a pseudorandom variable distributed according to the law of noncentral beta distribution the a, b and lambda parameters. In case of error it returns NaN.

double  MathRandomNoncentralBeta(
   const double  a,             // the first parameter of beta distribution (shape1)
   const double  b,             // the second parameter of beta distribution (shape2)
   const double  lambda,        // noncentrality parameter
   int&          error_code     // variable to store the error code
   );

Generates pseudorandom variables distributed according to the law of noncentral beta distribution the a, b and lambda parameters. In case of error it returns false. Analog of the rbeta() in R.
