Random convolution of O-exponential distributions

open access: yesNonlinear Analysis, 2015
Assume that ξ1, ξ2, ... are independent and identically distributed non-negative random variables having the O-exponential distribution. Suppose that η is a nonnegative non-degenerate at zero integer-valued random variable independent of ξ1, ξ2, ... . In

Efficient algorithms for calculating the probability distribution of the sum of hypergeometric-distributed random variables

open access: yesMethodsX, 2021
In probability theory and statistics, the probability distribution of the sum of two or more independent and identically distributed (i.i.d.) random variables is the convolution of their individual distributions.

Random convolution of inhomogeneous distributions with O-exponential tail

open access: yesModern Stochastics: Theory and Applications, 2016
Let $\{\xi _{1},\xi _{2},\dots \}$ be a sequence of independent random variables (not necessarily identically distributed), and η be a counting random variable independent of this sequence. We obtain sufficient conditions on $\{\xi _{1},\xi _{2},\dots \}$

Random Gaussian Sums on Trees

open access: yesElectronic Journal of Probability, 2011
Let $T$ be a tree with induced partial order $\preceq$. We investigate centered Gaussian processes $X=(X_t)_{t\in T}$ represented as $$ X_t=σ(t)\sum_{v \preceq t}α(v)ξ_v $$ for given weight functions $α$ and $σ$ on $T$ and with $(ξ_v)_{v\in T}$ i.i.d. standard normal.

Prediction of Components in Random Sums [PDF]

open access: yesMethodology and Computing in Applied Probability, 2016
We consider predictions of the random number and the magnitude of each iid component in a random sum based on its distributional structure, where only a total value of the sum is available and where iid random components are non-negative. The problem is motivated by prediction problems in a Poisson shot noise process.

On Random Sums of Random Vectors

open access: yesThe Annals of Mathematical Statistics, 1965
To obtain the limit distribution of a sequence $T_n$ of random vectors, the $j$th component of $T_n$ being the sum of a random number $N_n^{(j)}$ of $j$th components of independent, identically distributed chance vectors $X_n$, it is first necessary to treat the special case where the $N_n^{(j)}$ are degenerate random variables. This is done in Section

Sums of standard uniform random variables [PDF]

open access: yesJournal of Applied Probability, 2019
AbstractIn this paper, we analyse the set of all possible aggregate distributions of the sum of standard uniform random variables, a simply stated yet challenging problem in the literature of distributions with given margins. Our main results are obtained for two distinct cases.

Theoretical approach for uncertainty quantification in probabilistic safety assessment using sum of lognormal random variables

open access: yesNuclear Engineering and Technology, 2022
Probabilistic safety assessment is widely used to quantify the risks of nuclear power plants and their uncertainties. When the lognormal distribution describes the uncertainties of basic events, the uncertainty of the top event in a fault tree is ...

Asymptotics for Weighted Random Sums [PDF]

open access: yesAdvances in Applied Probability, 2012
Let {Xi} be a sequence of independent, identically distributed random variables with an intermediate regularly varying right tail F̄. Let (N, C1, C2,…) be a nonnegative random vector independent of the {Xi} with N∈ℕ∪ {∞}. We study the weighted random sum SN=∑{i=1}NCiXi, and its maximum, MN=sup{1≤kN+1∑i=1kCiXi.
