A new semiparametric test for superior predictive ability
We propose a new method to test the superior predictive ability (SPA) of a benchmark model against a large group of alternative models. The proposed test is useful for reducing potential data snoo** bias. Un...

Forecasting major Asian exchange rates using a new semiparametric STAR model
To forecast exchange rates, this paper proposes a new semiparametric smooth transition autoregressive model by allowing state variables to enter into the transition function in a nonparametric way. We propose ...

A model specification test for nonlinear stochastic diffusions with delay
This paper investigates model specification problems for nonlinear stochastic differential equations with delay (SDDE). Compared to the model specification for conventional stochastic diffusions without delay,...
