چکیده
|
We first propose in this paper a new test method for detecting heteroscedasticity of the error term in nonparametric regression. some simulation experiments are then conducted to evaluate the performance of the proposed methodology. a real-world data set is finally analyzed to demonstrate the application of the method. © 2014 si-lian shen et al.
