MathRandomHypergeometric

Generates a pseudorandom variable distributed according to the law of hypergeometric distribution with the m, n and k parameters. In case of error it returns NaN.

double  MathRandomHypergeometric(
   const double  m,              // total number of objects (integer)
   const double  k,              // number of objects with the desired characteristic (integer)
   const double  n,              // number of object draws (integer)
   int&          error_code      // variable to store the error code
   );

Generates pseudorandom variables distributed according to the law of hypergeometric distribution with the m, n and k parameters. In case of error it returns false. Analog of the rgeom() in R.

bool  MathRandomHypergeometric(
   const double  m,              // total number of objects (integer)
   const double  k,              // number of objects with the desired characteristic (integer)
   const double  n,              // number of object draws (integer)
   const int     data_count,     // amount of required data
   double&       result[]        // array with values of pseudorandom variables
   );
