As described in ArcGIS 10.2, the OHS analysis is a tool that uses the Getis-Ord Gi * statistic [Eq. (4)] to estimate the associated Z-score for each feature. To aggregate the Z-scores, OHS applies the average and the median nearest-neighbor calculations given incremental distances between observations as estimated using the incremental spatial autocorrelation tool. In the Getis-Ord Gi * statistic, x_jis the attribute value for the feature under consideration for observation j, w_{we, j} represents the spatial weights between observations, n is the total number of observations, X is equal to ? j = 1 n x j n , and S is equivalent to ? j = 1 n x j 2 n – ( X ) 2 .

To decide spatial weights representing spatial relationship anywhere between findings and you will between popular features of attention (Anselin, 1988; Getis and you can Aldstadt, 2004; Getis, 2009), i utilized the geo-referenced study-latitude and you may longitude regarding Haitian mladenka ranch and you can hold coordinates-built-up inside the profession survey and you can followed a-row-standard inverse range spatial weights matrix.
