Multinomial

scalation.random.Multinomial
case class Multinomial(p: Array[Double], n: Int, stream: Int) extends VariateVec

The Multinomial class generates random variate vectors following the multinomial distribution. This discrete RV models the multinomial trials, which generalize Bernoulli trials ({0, 1} to the case where the outcome is in {0, 1, ..., k-1}.

Value parameters

n

the number of independent trials

p

array of cumulative probabilities as CDF values

stream

the random number stream
