In this article asymptotic expressions for the final prediction error (FPE) and the accumulated prediction error (APE) of the least squares predictor are obtained in regression models with nonstationa...
Functional-coefficient models for nonstationary time series data
Nonstationary Nonlinearity Semiparametric estimation
2011/4/2
This paper studies functional coefficient regression models with nonstationary time series data, allowing also for stationary covariates. A local linear fitting scheme is developed to estimate the coe...
