A scan test for spatial groupwise heteroscedasticity in cross-sectional model...

We propose a scan test for the presence of spatial groupwise heteroskedasticity in cross-sectional data. The scan approach has been used in different fields before, including...本文提出一种用于检验截面数据（cross-sectional data）中空间分组异方差性（spatial groupwise heteroskedasticity）是否存在的扫描检验（scan test）方法。此前，该扫描方法已在包括……在内的诸多领域中得到应用。
