abstract = {We define a family of local mixing conditions that enable the computation of the extremal index of periodic sequences from the joint distributions of k consecutive variables of the sequence. By applying results, under local and global mixing conditions, to the (2m - 1)-dependent periodic sequence Xn(m) = Σj=-mm-1 cjZn-j, n ≥ 1, we compute the extremal index of the periodic moving average sequence Xn = Σj=-∞∞ cjZn-j, n ≥ 1, of random variables with regularly varying tail probabilities.This paper generalizes the theory for extremes of stationary moving averages with regularly varying tail probabilities.},

AB - We define a family of local mixing conditions that enable the computation of the extremal index of periodic sequences from the joint distributions of k consecutive variables of the sequence. By applying results, under local and global mixing conditions, to the (2m - 1)-dependent periodic sequence Xn(m) = Σj=-mm-1 cjZn-j, n ≥ 1, we compute the extremal index of the periodic moving average sequence Xn = Σj=-∞∞ cjZn-j, n ≥ 1, of random variables with regularly varying tail probabilities.This paper generalizes the theory for extremes of stationary moving averages with regularly varying tail probabilities.
