Abstract

To offer a more formal approach in line with classical statistical framework, the AA. develop an exact method for computing the p-values of the local Moran's Ii, local Geary's ci, and the modified Ord and Getis G statistics based on the distributional theory of quadratic forms in normal variables. Furthermore, an approximate method is also proposed to achieve a computational cost lower than the exact method. The study not only provides an exact test for local patterns of spatial association, but also puts the tests of several local statistics within a unified statistical framework
