Abstract
Consider the heteroscedastic regression model Y (j)(x in , t in ) = t in β + g(x in ) + σ in e (j)(x in ), 1 ≤ j ≤ m, 1 ≤ i ≤ n, where \({\sigma_{in}^{2}=f(u_{in})}\), (x in , t in , u in ) are fixed design points, β is an unknown parameter, g(·) and f(·) are unknown functions, and the errors {e (j)(x in )} are mean zero NA random variables. The moment consistency for least-squares estimators and weighted least-squares estimators of β is studied. In addition, the moment consistency for estimators of g(·) and f(·) is investigated.
