摘要:

The paper presents and compares two new very accurate and simple pairs of approximations for the Poisson modal probability and modal cumulative probability; these have been used by Kemp and Kemp (1987, 1988) for the generation of Poisson pseudorandom variables with varying noninteger parameter by the method of one-sided search from the mode. The approximations are rational except for the square root of an integer or half-integer.
