- _D_e_s_c_r_i_p_t_i_o_n:
-
- These functions provide information about the negative
- binomial distribution with parameters n and p. dnbinom
- gives the density, pnbinom gives the distribution func-
- tion qnbinom gives the quantile function and rnbinom
- generates random deviates.
-
- The negative binomial distribution has density
-
- p(x) = Choose(x+n-1,x) p^n (1-p)^x
-
- for x = 0, 1, 2, ...
