ABSTRACT In this article, we obtain a Stein operator for the sum of n independent random variables (rvs) which is shown as the perturbation of the negative binomial (NB) operator. Comparing the operator with NB operator, we derive the error bounds for total variation distance by matching parameters. Also, three-parameter approximation for such a sum is considered and is shown to improve the existing bounds in the literature. Finally, an application of our results to a function of waiting time… Expand
Approximation Results for Sums of Independent Random Variables.
In this article, we consider Poisson and Poisson convoluted geometric approximation to the sums of $n$ independent random variables under moment conditions. We use Stein's method to derive theExpand

Bounds on Negative Binomial Approximation to Call Function
In this paper, we develop Stein’s method for negative binomial distribution using call function defined by fz(k) = (k − z) + = max{k − z, 0}, for k ≥ 0 and z ≥ 0. We obtain error bounds betweenExpand
