| Abstract: | By considering the variance formula for a shifted reciprocal of a binomial proportion, the asymptotic expansions of any order for first negative moments of binomial and negative binomial distributions truncated at zero are obtained. The expansions are given in terms of the factorial powers of the number of trials  . The obtained formulae are more accurate than those of Marciniak and Weso owski (1999) and simpler, as they do not involve the Eulerian polynomials. |
