Convergence of moving average processes for dependent random variables. (English) Zbl 1219.60034

Summary: Let \(\{Y _{ i }, - \infty <i < \infty \}\) be a doubly infinite sequence of identically distributed random variables with \(E|Y _{1}| < \infty \), and \(\{a _{ i }, - \infty <i < \infty \}\) be an absolutely summable sequence of real numbers. Under dependence conditions on \(\{Y _{i}\}\), complete convergence and complete moment convergence of moving average process of the form \(X_k = \Sigma^\infty_{i=-\infty} a_{i+k} Y_i\) have been established by many authors. In this article, we give a general method for obtaining the complete moment convergence of the moving average process. Our result extends previous many results from dependent random variables to random variables satisfying some suitable conditions.
