You’ve probably heard of the Poisson distribution, a probability distribution often used for modeling counts, that is, … In probability theory and statistics, the Poisson distribution is a discrete probability distribution that expresses the probability of a given number of events occurring in a fixed interval of time or space if these events occur with a known constant mean rate and independently of the time since the … See more The distribution was first introduced by Siméon Denis Poisson (1781–1840) and published together with his probability theory in his work Recherches sur la probabilité des jugements en matière criminelle et en … See more Probability mass function A discrete random variable X is said to have a Poisson distribution, with parameter See more As a Binomial distribution with infinitesimal time-steps The Poisson distribution can be derived as a limiting case to the binomial distribution as the number of trials goes to infinity and the expected number of successes remains fixed — see law of … See more Applications of the Poisson distribution can be found in many fields including: • Count data in general • Telecommunication example: telephone calls arriving in a system. See more Descriptive statistics • The expected value and variance of a Poisson-distributed random variable are both equal to λ. • The coefficient of variation is See more Parameter estimation Given a sample of n measured values $${\displaystyle k_{i}\in \{0,1,\dots \},}$$ for i = 1, ..., n, we wish to estimate the value of the parameter λ of the Poisson population from which the sample was drawn.
