How Hot Spot Analysis (Getis-Ord Gi*) works - Esri
The Hot Spot Analysis (Getis-Ord Gi*) tool calculates the Getis-Ord Gi* statistic (pronounced G-i-star) for each feature in a dataset. The resultant z-scores and p-values indicate where features with either high or low values cluster spatially.
Getis–Ord statistics - Wikipedia
Getis–Ord statistics, also known as Gi*, are used in spatial analysis to measure the local and global spatial autocorrelation. Developed by statisticians Arthur Getis and J. Keith Ord they are commonly used for Hot Spot Analysis[1][2] to identify where features with high or low values are spatially clustered in a statistically significant way.

17.4 Getis-Ord Statistics. An early class of statistics for local spatial autocorrelation was proposed by Getis and Ord , and further elaborated upon in Ord and Getis . It is derived from a point pattern analysis logic.
Hot Spot Analysis (Getis-Ord Gi*) (Spatial Statistics) - Esri
Given a set of weighted features, identifies statistically significant hot spots and cold spots using the Getis-Ord Gi* statistic. This tool identifies statistically significant spatial clusters of high values (hot spots) and low values (cold spots).
