For example, one talks about "a Poisson distribution with mean value λ". Source: Internet

For occurrences of “contagious” discrete events, like tornado outbreaks, the Polya distributions can be used to give more accurate models than the Poisson distribution by allowing the mean and variance to be different, unlike the Poisson. Source: Internet

Hence a Poisson distribution is not an appropriate model. Source: Internet

His significant publications include: * In 1909 - "The Theory of Probabilities and Telephone Conversations" - which proves that the Poisson distribution applies to random telephone traffic. Source: Internet

If the null hypothesis predicts (say) on average 9 counts per minute, then according to the Poisson distribution typical for radioactive decay there is about 41% chance of recording 10 or more counts. Source: Internet

In such cases, the observations are overdispersed with respect to a Poisson distribution, for which the mean is equal to the variance. Source: Internet
