Definition of Poisson distribution in English:
Poisson distribution
nounˈpwʌsɒ̃pwäˈsän ˌdistrəˌbyo͞oSH(ə)n
Statistics A discrete frequency distribution which gives the probability of a number of independent events occurring in a fixed time.
Example sentencesExamples
- Note that the numbers of mutations and gene conversion events per generation follow Poisson distributions.
- In this he was the first to note that events with low frequency in a large population followed a Poisson distribution even when the probabilities of the events varied.
- The Poisson distribution provides a statistical description of the number of enzymes in the droplet.
- By using recurrence relations for the probability distributions, they show that in several cases the numbers of homozygous and heterozygous loci have independent Poisson distributions.
- Because of the extreme non-normality of these scores, we used a statistical test for two Poisson distributions.
Origin
Late 19th century: named after the French mathematical physicist Siméon-Denis Poisson( 1781–1840).
