Function rnbinom

rnbinom(
    n: number,
    size: number,
    options: { mu?: number; prob?: number },
): number[]
Random numbers from the negative binomial distribution. Equivalent to R's rnbinom().
Parameters
- n: number
  Number of values to generate (fractions are truncated, as in R).
- size: number
  Target number of successes (dispersion parameter; need not be an integer).
- options: { mu?: number; prob?: number }
  - Optionalmu?: number
    
    Mean (alternative parametrization). Give exactly one of prob and mu.
  - Optionalprob?: number
    
    Probability of success in each trial. Give exactly one of prob and mu.
Returns number[]
An array of n values; NaN for invalid parameters.
Throws
TypeError unless exactly one of prob and mu is given.
Example
```
setSeed(1);
rnbinom(5, 3, { prob: 0.5 }); // [3, 2, 2, 2, 2]
rnbinom(5, 3, { mu: 2 });
```
