Super-Poissonian distribution : ウィキペディア英語版 | Super-Poissonian distribution In mathematics, a super-Poissonian distribution is a probability distribution that has a larger variance than a Poisson distribution with the same mean. Conversely, a sub-Poissonian distribution has a smaller variance. An example of super-Poissonian distribution is negative binomial distribution.〔Simon Anders and Wolfgang Huber. Differential expression analysis for sequence count data. Genome Biology 2010, 11:R106; doi:10.1186/gb-2010-11-10-r106〕 The Poisson distribution is a result of a process where the time (or an equivalent measure) between events has an Exponential distribution, representing a memoriless process.
