Detecting spatial heteroscedasticity in geographically weighted regression model

摘要：

Based on residuals of geographically weighted regression calibration a testing method is proposed to detect spatially heteroscedasticity in the spatially varying coefficient regression model.The three-moment x2-approximation is employed to derive p-value of the test.
