1914Ark. för Matem., Astr. och Fysik IX. xxv. 16 Repeating the experiment r times we obtain respectively m1, m2, m3,{ddd}, mr white balls in these r sets. These numbers form what is called a Poissonian series. 1951Jrnl. R. Statistical Soc. B. XIII. 168 If they call for service in a random manner the input-process (while q customers are waiting or being served) will be Poissonian, but will depend on the value of q. 1972Science 2 June 1034/1 The Poissonian probability times the efficiency of plating gave an actual distribution of ≤ 0·3 cell per well. 1976Physics Bull. Mar. 111/1 If T was short compared with the inverse spectral linewidth of a random source, a geometric distribution was obtained while if T was long the photon counting distribution became Poissonian due to averaging of the photon arrivals. |
