摘要
以地理加权回归模型为基础,通过假定其中回归变量的系数是地理位置的任意函数,给出了选取权函数的原则和确定窗宽参数的交叉确认法,并且讨论了它们的作用.
Based upon geographically weighted regression model,this paper gives the principle of selecting weighting function and cross-validation procedure of determining bandwidth parameter and discusses their action by assuming the coefficients of the regressors to be arbitrary function of geography location.
