The Displaced Poisson Distribution—Region B
移位泊松分布：B 参数区域
The two-parameter (λ, r) probability function which arises from a generalization, px =λpx -1/(x+r), of the recurrence relationship between successive probabilities of a Poisson process, has been termed the ‘Displaced Poisson Distribution’ and is considered here over the parameter space λ > 0, r ≤ 0. Properties of the distribution are examined and estimators, when r is known and unknown, are derived by the methods of moment(s) and first frequency and by maximum likelihood.…
