The '''Borel distribution''' is a [[discrete probability distribution]], arising in contexts including [[branching processes]] and [[queueing theory]].
 
If the number of offspring that an organism has is [[Poisson distribution|Poisson-distributed]], and if the average number of offspring of each organism is no bigger than&nbsp;1, then the descendants of each individual will ultimately become extinct. The number of descendants that an individual ultimately has in that situation is a random variable distributed according to a Borel distribution.
 
==Definition==
A discrete [[random variable]] ''X{{space}}'' is said to have a Borel distribution<ref>{{cite journal | first = Émile | last = Borel | authorlink = Émile Borel | title = Sur l’emploi du théorème de Bernouilli pour faciliter le calcul d’une infinité de coefficients.

with parameter ''μ''&nbsp;∈&nbsp;[0,1] if the [[probability mass function]] of ''X'' is given by

for ''n''&nbsp;=&nbsp;1,&nbsp;2,&nbsp;3&nbsp;....
 
==Derivation and branching process interpretation==
If a [[branching process|Galton–Watson branching process]] has common offspring distribution [[Poisson distribution|Poisson]] with mean ''μ'', then the total number of individuals in the branching process has Borel distribution with parameter ''μ''.
 
Let ''X{{space}}'' be the total number of individuals in a Galton–Watson branching process.  
Then a correspondence between the total size of the branching process and a hitting time for an associated random walk<ref>{{cite doi|10.1214/aoms/1177730031}}</ref><ref name=Dwass>{{cite jstor| 3212112}}</ref><ref name=Pitman>{{cite journal | first = Jim | last =Pitman

where ''S''<sub>''n''</sub>&nbsp;=&nbsp;''Y''<sub>1</sub>&nbsp;+&nbsp;…&nbsp;+&nbsp;''Y''<sub>''n''</sub>, and ''Y''<sub>1</sub>&nbsp;…&nbsp;''Y''<sub>''n''</sub> are [[independent identically distributed random variables]] whose common distribution is the offspring distribution of the branching process.  
In the case where this common distribution is Poisson with mean ''μ'', the random variable
''S''<sub>''n''</sub> has Poisson distribution with mean ''μn'',
leading to the mass function of the Borel distribution given above.  
 
Since the ''m''th generation of the branching process has mean size ''μ''<sup>''m''&nbsp;−&nbsp;1</sup>,
the mean of ''X{{space}}'' is

==Queueing theory interpretation==
In an [[M/D/1 queue]] with arrival rate ''μ'' and common service time 1,
the distribution of a typical busy period of the queue is Borel with parameter ''μ''.

==Properties==
If ''P''<sub>''μ''</sub>(''n'') is the probability mass function of a
Borel(''μ'') random variable, then the mass function
''P''{{su|p=&lowast;|b=''&mu;''}}(''n'')
of a sized-biased sample from the distribution
(i.e. the mass function proportional to ''nP''<sub>''&mu;''</sub>(''n'')&nbsp;)
is given by
 
:<math>P_\mu^*(n)=(1-\mu)\frac{e^{-\mu n}(\mu n)^{n-1}}{(n-1)!}.</math>
 
Aldous and Pitman
<ref>{{cite doi|10.1016/S0246-0203(98)80003-4}}</ref>
show that
 
:<math>P_\mu(n)=\frac{1}{\mu}\int_0^{\mu}P_\lambda^*(n) \, d\lambda.</math>
 
In words, this says that a Borel(''μ'') random variable has the same distribution
as a size-biased Borel(''μU'') random variable, where ''U'' has the uniform distribution on [0,1].
 
This relation leads to various useful formulas, including
 
:<math>E(1/X) = 1-\mu/2.</math>
 
==Borel–Tanner distribution==
The '''Borel–Tanner distribution''' generalizes the Borel distribution.
Let ''k'' be a positive integer.  
If ''X''<sub>1</sub>,&nbsp;''X''<sub>2</sub>, &nbsp;…&nbsp;''X''<sub>''k''</sub>
are independent and each has
Borel distribution with parameter ''μ'', then their sum
''W''&nbsp;=&nbsp;''X''<sub>1</sub>&nbsp;+&nbsp;''X''<sub>2</sub>&nbsp;+&nbsp;…&nbsp;+&nbsp;''X''<sub>''k''</sub> is said to have Borel–Tanner distribution with parameters ''μ'' and ''k''.
<ref>{{cite doi|10.1093/biomet/40.1-2.58}}</ref><ref name="Tanner1961" /><ref name=HaightBreuer />
This gives the distribution of the total number of individuals
in a Poisson–Galton–Watson process starting with ''k'' individuals in the first generation,
or of the time taken for an M/D/1 queue to empty starting with ''k'' jobs in the queue.
The case ''k''&nbsp;=&nbsp;1 is simply the Borel distribution above.

:<math>\Pr(W=n)=\frac{k}{n}\Pr(S_n=n-k)</math>
 
where ''S''<sub>''n''</sub> has Poisson distribution with mean ''nμ''.
As a result the probability mass function is given by
