Periodic moving average process [PDF]

open access: yesApplications of Mathematics, 1985
Periodic moving average processes are representatives of the class of periodic models suitable for the description of some seasonal time series and for the construction of multivariate moving average models. The attention being lately concentrated mainly on the periodic autoregressions, some methods of statistical analysis of the periodic moving ...

On the structure of moving average processes [PDF]

open access: yesJournal of Econometrics, 1977
This paper uses Hilbert space methods to develop a rigorous proof that the sum of two uncorrelated moving average processes of order q1 and qz is an MA process of order q 6 max ((I~, q2). The methods establish the existence of suitable random shocks for the summed process, they illuminate relationships between the coefficients of such processes and ...

Complete moment convergence of moving average processes for m-WOD sequence

open access: yesJournal of Inequalities and Applications, 2021
In this paper, the complete moment convergence for the partial sum of moving average processes { X n = ∑ i = − ∞ ∞ a i Y i + n , n ≥ 1 } $\{X_{n}=\sum_{i=-\infty }^{\infty }a_{i}Y_{i+n},n\geq 1\}$ is established under some mild conditions, where { Y i , −

Bayesian Prediction of Moving Average Processes Using Different Types of Priors [PDF]

open access: yesThe Egyptian Statistical Journal, 2018
The current article approaches the Bayesian prediction of moving average processes using three well-known priors: g prior, natural conjugate (NC) prior, and Jeffreys' prior.

Bayesian Classification with First Order Moving Average Sources [PDF]

open access: yesThe Egyptian Statistical Journal, 1992
The main objective of this paper is to develop a convenient Bayesian procedure that can be used to assign a univariate time series realization to one of several first order moving average sources, with unknown coefficients, that share a common unknown ...

Box-Jenkins Forecasting Arima Models as Applied to Commercial Banks' Deposits [PDF]

open access: yesThe Egyptian Statistical Journal, 1992
The Box-Jenkins ARIMA model is used in this article to identify statistical forecasting models for the commercial banks deposits in Egypt. Four models have been identified according to the type of the sun deposits.

A Closed Analytic for the Precision Matrix of the Second Order Moving Average Processes [PDF]

open access: yesThe Egyptian Statistical Journal, 2018
A difficult and challenging problem not only to bayesian but also to those interested in maximum likelihood estimation is to express the precision matrix of the second order moving average processes in closed analytic from in terms of the parameters ...

An EWMA control chart for the mean of individual streams in multiple stream processes

open access: yesGestão & Produção, 2021
: In a multiple stream process (MSP) a product is manufactured in a number of streams in parallel. The traditional tool for monitoring MSPs, the group control chart (GCC), does not take into account that typically the value of the quality variable in ...

Exponentially weighted moving average—Moving average charts for monitoring the process mean

open access: yesPLOS ONE, 2020
This research aimed to propose a newly-mixed control chart called the Exponentially Weighted Moving Average-Moving Average Chart (EWMA-MA) to detect the mean change in a process underlying symmetric and asymmetric distributions. The performance of the proposed control chart are compared with Shewhart, MA, EWMA, MA-EWMA and EWMA-MA control charts by ...
