摘要
Considered he semiparametric regression model l(i) = A(i)(T)X + s(t(i)) + Delta(i) (i = 1, 2,...,n). Firstly, ridge estimators of both parameters and nonparameters are attained without a restrained design matrix. Secondly, the ridge estimator will be compared with two steps estimation under a mean square error and some conditions in which the former excels the latter are given. Finally, the validity and feasibility of the method are illustrated by a simulating example. (C) 2004 Published by Elsevier B.V.
