| Abstract: | Semivarying coefficient models have been discussed in many papers and applied widely in many fields. In recent years, many approaches are developed to estimate the unknown parameters and the coefficient functions. Based on the profile least squares method, the constrained profile least squares estimation on semivarying coefficient models under linear stochastic constraints is developed in this paper. Asymptotic normalities of the estimation on parametric component and nonparametric component are investigated. |
