The Pascal Distribution

Random: unsigned int gsl_ran_pascal (const gsl_rng * r, double p, unsigned int k)
This function returns a random integer from the Pascal distribution. The Pascal distribution is simply a negative binomial distribution with an integer value of @math{n}.

for @c{$k \ge 0$} @math{k >= 0}

Function: double gsl_ran_pascal_pdf (unsigned int k, double p, unsigned int n)
This function computes the probability @math{p(k)} of obtaining k from a Pascal distribution with parameters p and n, using the formula given above.
