Function rmultinom

rmultinom(n: number, size: number, prob: readonly number[]): number[][]
Random vectors from the multinomial distribution. Equivalent to R's rmultinom().

Unlike R, which returns a K x n matrix with one draw per column, this returns n rows with one draw per row (the transpose of R's result). The random stream is the same as R's.
Parameters
- n: number
  Number of values to generate (fractions are truncated, as in R).
- size: number
  Number of objects distributed into the K categories in each draw (fractions are truncated, as in R).
- prob: readonly number[]
  Category weights of length K. They need not sum to 1 (they are divided by their sum).
Returns number[][]
An array of n arrays, each of length K and summing to the truncated size.
Throws
RangeError if the truncated size is negative or 2^31 or more, or prob has a negative or non-finite value, or no positive value.
Example
```
setSeed(1);
rmultinom(2, 5, [0.2, 0.3, 0.5]); // [[0, 1, 4], [1, 3, 1]]
```
