About this document
G Statistics for Spatial Association Analysis by Yemerith Alpízar Segura is a document available to read on EtoBox.
The document introduces the G statistics, which can measure spatial association within a specified distance of a single point. Specifically, it defines the Gi(d) statistic, which measures the concentration of weighted points within distance d of point i, excluding point i itself. It derives the expected value and variance of Gi(d) and shows that under the null hypothesis of spatial independence, Gi(d) will approach a normal distribution as the number of points increases, provided the conditions for normalit
