Among all discrete probability distributions supported on {1, 2, 3, ... } with given expected value μ, the geometric distribution X with parameter p = 1/μ is the one with the largest entropy. See more In probability theory and statistics, the geometric distribution is either one of two discrete probability distributions: • The probability distribution of the number X of Bernoulli trials needed to get one success, supported … See more Consider a sequence of trials, where each trial has only two possible outcomes (designated failure and success). The probability of success is assumed to be the same for each trial. In such a sequence of trials, the geometric distribution is useful … See more Parameter estimation For both variants of the geometric distribution, the parameter p can be estimated by … See more Geometric distribution using R The R function dgeom(k, prob) calculates the probability that there are k failures before the first success, where the argument "prob" is the probability of success on each trial. For example, See more Moments and cumulants The expected value for the number of independent trials to get the first success, and the variance of a geometrically distributed See more • The geometric distribution Y is a special case of the negative binomial distribution, with r = 1. More generally, if Y1, ..., Yr are independent geometrically distributed variables with parameter p, then the sum $${\displaystyle Z=\sum _{m=1}^{r}Y_{m}}$$ See more • Hypergeometric distribution • Coupon collector's problem • Compound Poisson distribution See more
