چکیده

where both m(·) and σ(·) are unknown functions defined over R, the data {(Xt, Yt)}t=1 are weakly dependent stationary time series, and et is an error process with zero mean and unit variance. Suppose that {mθ(·)|θ ∈ Θ} is a family of parametric specification to the regression function m(x) where θ ∈ R is an unknown parameter belonging to a parameter space Θ. This paper considers testing the validity of the parametric specification of mθ(x) against a series of local alternatives, that is to test

An Adaptive Empirical Likelihood Test for Parametric Time Series Regression Models

A test for a parametric regression model against a sequence of local alternative is constructed based on an empirical likelihood test statistic that measures the goodness-of-fit between the parametric model and its nonparametric counterpart. To reduce the dependence of the test on a single smoothing bandwidth, the test is formulated by maximizing a standardized version of the empirical likeliho...

Which Methodology is Better for Combining Linear and Nonlinear Models for Time Series Forecasting?

Both theoretical and empirical findings have suggested that combining different models can be an effective way to improve the predictive performance of each individual model. It is especially occurred when the models in the ensemble are quite different. Hybrid techniques that decompose a time series into its linear and nonlinear components are one of the most important kinds of the hybrid model...
