The Stein-Chen method is usedto give new bounds, non-uniform bounds, for the distances between the distribution of a sum of independent negative binomial random variables and a Poisson distribution with mean, ∑ni=1riqi –pi
where ri and pi =1 - qiare parameters of each negative binomial distribution. Results of this study are superior than those presented in Teerapabolarn (2014) and Hung and Giang (2016).
