Specifying Smooth Transition Regression Models in the Presence of Conditional Heteroskedasticity of Unknown Form [PDF]

The specification of Smooth Transition Regression models consists of a sequence of tests, which are typically based on the assumption of i.i.d. errors. In this paper we examine the impact of conditional heteroskedasticity and investigate the performance ...
