* Global coefficients correspond to values obtained using the ordinary least squares method, which does not consider spatial heterogeneity
** Number of districts where GWR coefficients were statistically significant among 249 districts in which their local t-values exceeded 1.96 or were below 鈭掆€�1.96
Notes: GWR, geographically weighted regression; AIC, Akaike information criterion; AICc, Akaike information criterion with correction. All variables are standardized. The GWR was performed based on a fixed bandwidth (=鈥�76.921 Km) with a Gaussian Kernel function
