Function dmultinom

dmultinom(
    x: readonly number[],
    prob: readonly number[],
    options?: MultinomialOptions,
): number
Probability function of the multinomial distribution. Equivalent to R's dmultinom(x, size = NULL, prob, log = FALSE).
Parameters
- x: readonly number[]
  Counts, a vector of K non-negative integers.
- prob: readonly number[]
  Category weights, K finite non-negative numbers, not all 0 (divided by their sum).
- options: MultinomialOptions = {}
  size and log (see MultinomialOptions).
Returns number
The probability N! / (x_1! ... x_K!) prod p_j^x_j with N = sum(x), or its log.
Throws
RangeError if x and prob differ in length, x has a negative or non-integer value, prob has a negative or non-finite value or no positive value, or size differs from the sum of x.
Example
```
dmultinom([1, 2, 1], [0.2, 0.5, 0.3]);  // 0.18000000000000002
```
