Abstract. Consider the nonparametric regression modelis an unknown regression function, x ni are known fixed design points, and the correlated errors {ϵ ni , 1 ≤ i ≤ n} have the same distribution as {V i , 1 ≤ i ≤ n}, here Vt = P ∞ j=−∞ ψ j e t−j with P ∞ j=−∞ |ψ j | < ∞ and {et} are negatively associated random variables. Under appropriate conditions, we derive a Berry-Esseen type bound for the estimator of g(·). As corollary, by choice of the weights, the BerryEsseen type bound can attain O(n −1/4 (log n) 3/4 ).
