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 $${\textstyle \lambda ^{-1/2},}$$ while the index of dispersion is 1. 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. The See more The Poisson distribution poses two different tasks for dedicated software libraries: evaluating the distribution $${\displaystyle P(k;\lambda )}$$, and drawing random … See more
