Abstract
The following heteroscedastic regression model Y i = g(x i) + σ i e i (1 ≤ i ≤ n) is considered, where it is assumed that σ 2i = f(u i), the design points (x i, u i) are known and nonrandom, g and f are unknown functions. Under the unobservable disturbance e i form martingale differences, the asymptotic normality of wavelet estimators of g with f being known or unknown function is studied.
