Abstract:
|
The purpose of this talk is to present our latest investigation about two-fold nonparametric nested models. The testing of the subclass effects when the number of subclasses is large is the core of this talk. We start from the homoscedastic balanced cases, and then move on to the heteroscedastic unbalanced cases, in which two different approaches are proposed and compared. Not only the fixed-effects models but also the random-effects and mixed-effects models are studied.
