SummaryConsider mutually independent inputsX1,...,Xn onn different occasions into a dam or storage facility. The total input isY=X1+...+Xn. This sum is a basic quantity in many types of stochastic process problems. The distribution ofY and other aspects connected withY are studied by different authors when the inputs are independently and identically distributed exponential or gamma random variables. In this article explicit exact expressions for the density ofY are given whenX1,...,Xn are… 

Density and distribution evaluation for convolution of independent gamma variables

The Kummer confluent hypergeometric function is demonstrated to be computationally most efficient and a new computationally efficient formula is derived for the probability mass function of the number of renewals by a given time.

Density and distribution evaluation for convolution of independent gamma variables

Convolutions of independent gamma variables are encountered in many applications such as insurance, reliability, and network engineering. Accurate and fast evaluations of their density and

System availability in a gamma alternating renewal process

We measure the effectiveness of a repairable system by the proportion of time the system is on, where on-time and off-times are assumed independent and both gamma-distributed. This measure is helpful

The Distribution of the Sum of Independent Product of Bernoulli and Exponential

SYNOPTIC ABSTRACT The product of the independent Bernoulli and exponential random variables (rv's), has received great attention in recent literature, in particular because of its applications in

An approximation to the convolution of gamma distributions

A general negative binomial distribution is suggested to approximate Moschopoulos’s expression looking for an approximating theoretical discrete distribution for the weights of the series and is an “excellent” approximation, fast and simple to implement for any parameter combination.

Notes on the sum and maximum of independent exponentially distributed random variables with different scale parameters

We consider the distribution of the sum and the maximum of a collection of independent exponentially distributed random variables. The focus is laid on the explicit form of the density functions

THE EXACT DISTRIBUTION OF SUMS WEIGHTS OF GAMMA VARIABLES

We consider a representation of the probability density func- tion of a weighted convolution of the gamma distribution, where a con- fluent hypergeometric function describes how the differences

The Distributions of Sums for Shanker, Akash, Ishita, Pranav, Rani, and Ram Awadh

In statistics and probability theory, one of the most important statistics is the sums of random variables. After introducing a probability distribution, determining the sum of n independent and

Estimation of multivariate generalized gamma convolutions through Laguerre expansions

The generalized gamma convolutions class of distributions appeared in Thorin’s work while looking for the infinite divisibility of the logNormal and Pareto distributions. Although these distributions
