Binomial and hypergeometric distributions
WebIn probability theory and statistics, the negative binomial distribution is a discrete probability distribution that models the number of failures in a sequence of independent … WebThe Hypergeometric Distribution Expression (3.16) shows that the means of the binomial and hypergeometric rv’s are equal, whereas the variances of the two rv’s differ by the factor (N –n)/(N –1), often called the finite population correction factor.
