Input Feature Class
The feature class for which hot spot analysis will be performed.
The numeric field (number of victims, crime rate, test scores, and so on) to be evaluated.
Output Feature Class
The output feature class to receive the z-score and p-value results.
Conceptualization of Spatial Relationships
Specifies how spatial relationships among features will be defined.
Specifies how distances will be calculated from each feature to neighboring features.
Row standardization has no impact on this tool: results from Hot Spot Analysis (the Getis-Ord Gi* statistic) would be identical with or without row standardization. The parameter is disabled; it remains as a tool parameter only to support backward compatibility.
Distance Band or Threshold Distance
Specifies a cutoff distance for the inverse distance and fixed distance options. Features outside the specified cutoff for a target feature will be ignored in analyses for that feature. However, for Zone of indifference, the influence of features outside the given distance will be reduced with distance, while those inside the distance threshold will be equally considered. The distance value entered should match that of the output coordinate system.
For the inverse distance conceptualizations of spatial relationships, a value of 0 indicates that no threshold distance will be applied; when this parameter is left blank, a default threshold value will be computed and applied. The default value is the Euclidean distance, which ensures that every feature has at least one neighbor.
This parameter has no effect when polygon contiguity (Contiguity edges only or Contiguity edges corners) or Get spatial weights from file spatial conceptualization is selected.
Self Potential Field
The field representing self potential: the distance or weight between a feature and itself.
Weights Matrix File
The path to a file containing weights that define spatial, and potentially temporal, relationships among features.
Apply False Discovery Rate (FDR) Correction
Specifies whether statistical significance will be assessed with or without FDR correction.
Number of Neighbors
An integer specifying the number of neighbors to include in the analysis.
The results field name (GiZScore).
The probability field name (GiPValue).
The source ID field name (SOURCE_ID).
