Asymptotics for randomly weighted and stopped dependent sums

Stochastics, 2015
This paper deals with the tail probability of , where is a sequence of extended negatively upper orthant dependent or bivariate upper tail independent, identically distributed random variables with dominatedly varying tails, is a sequence of nonnegative nondegenerate at zero random variables (not necessarily independent and identically distributed), is

Tail areas for randomly stopped sums defined on a Markov chain

Communications in Statistics. Stochastic Models, 1993
Summary: A saddlepoint approximation is provided for the tail area \(P\left\{\sum^ N_ 1X_ k>y\right\}\) where the \(S_ n=\sum^ n_ 1X_ k\) form a random walk on a Markov chain and \(N\), which is independent of the \(X_ k\), has a negative binomial distribution.

Finiteness of moments of randomly stopped sums of i.i.d. random variables

Statistics & Probability Letters, 1989
Let \(\{X_ n\), \(n\geq 1\}\) be independent, identically distributed random variables such that \(E(X)=0\), and let \(Z_ n=\sum^{n}_{i=1}X_ i\). If N is a stopping time for \(\{X_ n\}\), \(Z_ N\) is called a randomly stopped sum. The main result of this paper states that for \(r\in (0,\infty)\) and \(a\in [1,2]\), \(E(N^{r/a})

On a conjecture for the non-existence of the expectation of randomly stopped sums

Journal of Applied Probability, 1995
In a recent paper on the validity of Wald's equation, Roters (1994) raised an important question on the non-existence of the expectation of randomly stopped sums. The purpose of this note is to answer the question in the affirmative. As a consequence, an old question by Taylor (1972) also gets a positive answer.
