Lumping Processes of Periodic ARMA Processes

Authors: Smadi, Abdullah A. عبد الله الصمادي;

Lumping Processes of Periodic ARMA Processes

Abstract

In this article various lumping processes are defined for periodic ARMA (PARMA) processes, namely, the forward, the backward and the cyclic lumping processes. The inter-relations between the parameters of these lumping processes are obtained. It is then proved that stationarity of any lumped process implies sta¬tionarity of all other lumped processes. في هذا البحث تمت مقارنة ثلاث عمليات تراكمية لعمليات ( PARMA ‏) وهي العملية الأمامية، العملية العكسية والعملية الدورية، لقد توصلنا إلى العلاقات الثنائية التي تربط ما بين معلمات كل ‏من هذه العمليات التراكمية كما تم إثبات أن استقرار أي من هذه العمليات يؤدي إلى أن العمليات الأخرى ص أيضأ مستقرة.
