negativeBinomial

negativeBinomial(mu: number, sigma: number) 🡒 ranvar, pure function

Returns the negative binomial distribution of mean mu and of standard deviation sigma. If the standard deviation is smaller than the square root of the team, then a Poisson distribution of the specified mean is returned instead (hence ignoring the sigma).
