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 and … In probability theory and statistics, the binomial distribution with parameters n and p is the discrete probability distribution of the number of successes in a sequence of n independent experiments, each asking a yes–no question, and each with its own Boolean-valued outcome: success (with probability p) or failure … See more Probability mass function In general, if the random variable X follows the binomial distribution with parameters n ∈ $${\displaystyle \mathbb {N} }$$ and p ∈ [0,1], we write X ~ B(n, p). The probability of getting exactly k … See more Estimation of parameters When n is known, the parameter p can be estimated using the proportion of successes: See more Methods for random number generation where the marginal distribution is a binomial distribution are well-established. One way to generate See more This distribution was derived by Jacob Bernoulli. He considered the case where p = r/(r + s) where p is the probability of success and r and s are positive integers. Blaise Pascal had earlier considered the case where p = 1/2. See more Expected value and variance If X ~ B(n, p), that is, X is a binomially distributed random variable, n being the total number of experiments and p the probability of each experiment yielding a successful result, then the expected value of X is: See more Sums of binomials If X ~ B(n, p) and Y ~ B(m, p) are independent binomial variables with the same probability p, then X + Y is again a binomial variable; its distribution is Z=X+Y ~ B(n+m, p): See more • Mathematics portal • Logistic regression • Multinomial distribution See more
