Abstract: In geographically and temporally weighted regression model, the estimates of the
coefficients are obtained by geographically weighted fitting technique where spatial-temporal
weighted distance is used in weighted matrix. Then, appropriate statistics for testing the
temporal and spatial nonstationarity of the estimated coefficients are proposed and the p values
are calculated with the third-order moment Χ2 approximation method. Finally, the simulation
example and real example show that the test methods are valid.
