Abstract
This paper is concerned with a semiparametric regression model Yi = θ1+θ2(Ti)+εi, i = 1, ⋯, n where the error εi is independent of Ti for each i, θ1 is an unknown constant of interest, and θ2 is an unknown function on [0, 1]. In order to obtain an asymptotically efficient estimate θ̂1wof θ1, θ2(t) is generally in the literature assumed to be a continuously differentiable function on [0, 1]. In this paper, it is constructed assuming only that θ2 is an unknown piecewise differentiable function on [0, 1]. In the process of construction, wavelet expansion is employed.
