### 20.34 The Pascal Distribution

Function: unsigned int gsl_ran_pascal (const gsl_rng * r, double p, unsigned int n)

  This function returns a random integer from the Pascal distribution. The Pascal distribution is simply a negative binomial distribution with an integer value of n. for k >= 0

Function: double gsl_ran_pascal_pdf (unsigned int k, double p, unsigned int n)

  This function computes the probability p(k) of obtaining k from a Pascal distribution with parameters p and n, using the formula given above.

Function: double gsl_cdf_pascal_P (unsigned int k, double p, unsigned int n)
Function: double gsl_cdf_pascal_Q (unsigned int k, double p, unsigned int n)

  These functions compute the cumulative distribution functions P(k), Q(k) for the Pascal distribution with parameters p and n.
