| Abstract: | The regression coefficients in mixed geographically weighted regression model characterize by that portion of its regression coefficients are unknown constants while other regression coefficients are unknown functions of geographical locations.On the basis of this characteristics of coefficients,two simple and effective methods,backfeed method and two-step estimation method,were given for estimation of the dependent variables in the model. |
