Consider the nonparametric regression model with repeated measurements: Y-(j)(x(ni)) = g (x(ni)) + e((j)) (x(ni)), where Y-(j)(x(ni)) is the jth response at the point x(ni), x(ni)'s are known and nonrandom, and g(.) is unknown function defined on a closed interval [0, 1]. For exhibiting the correlation among the units and avoiding any assumptions among the observations within the same unit, we consider the model with negative associated (NA) error structures, that is, {e((j))(x), j >= 1} is a mean zero NA error process. The wavelet procedures are developed to estimate the regression function. Some asymptotics of wavelet estimator are established under suitable conditions.
