Brit.

/pwɑːˈsəʊnɪən/,

/pwaˈsəʊnɪən/, U.S.

Origin: From a proper name, combined with an English element. Etymons: proper name Poisson , -ian suffix.

Etymology: < the name of Siméon-Denis Poisson (see Poisson n.) + -ian suffix.

Mathematics.

Of, relating to, or of the nature of a Poisson distribution.

1972 Science 2 June 1034/1 The Poissonian probability times the efficiency of plating gave an actual distribution of ≦ 0·3 cell per well.

1991 Q. Jrnl. Royal Astron. Soc. 32 93 We have now found at least a partial answer to the question: If the distribution of galaxies is not Poissonian, then what is it?
