Abstract
Two interesting results encountered in the literature concerning the Poisson and the negative binomial distributions are due to MORAN (1952) and PATIL & SESHADRI (1964), respectively.
MORAN's result provided a fundamental property of the Poisson distribution. Roughly speaking, he has shown that if Y, Z are independent, nonnegative, integervalued random variables with X=Y  Z then, under some mild restrictions, the conditional distribution of Y  X is binomial if and only if Y, Z are Poisson random variables.
Motivated by MORAN's result PATIL & SESHADRI obtained a general characterization. A special case of this characterization suggests that, with conditions similar to those imposed by MORAN, Y  X is negative hypergeometric if and only if Y, Z are negative binomials.
In this paper we examine the results of MORAN and PATIL & SESHADRI in the case where the conditional distribution of Y  X is truncated at an arbitrary point k1 (k=1, 2, …). In fact we attempt to answer the question as to whether MORAN's property of the Poisson distribution, and subsequently PATIL & SESHADRI's property of the negative binomial distribution, can be extended, in one form or another, to the case where Y  X is binomial truncated at k1 and negative hypergeometric truncated at k1 respectively
