Abstract: | Abstract
In this paper, we discuss the moving-average process
, where {α
i
;-∞ < i < ∞} is a doubly infinite sequence of identically distributed φ-mixing or negatively associated random variables with mean
zeros and finite variances, {α
i
;-∞ < i < ∞} is an absolutely summable sequence of real numbers. Set
. Suppose that
. We prove that for any
, , and if
, where
is a Gamma function and μ(2δ+2) stands for the (2δ + 2)-th absolute moment of the standard normal distribution.
