000846 : <value> feature(s) had no neighbors which generally invalidates the statistical properties of a test.

Description

Some analytic tools assess each feature within the context of "neighboring" features. Feature distances are computed based on the true geometric centroids for each feature. Some features for this dataset have no neighboring features within the given specified distance threshold and/or using the specified Conceptualization of Spatial Relationships option.

Solution

(1) Use a larger distance band threshold, (2) select a Conceptualization of Spatial Relationships value that will ensure each feature has at least one neighbor, or (3) define spatial relationships using the Generate Spatial Weights Matrix tool. Run the tool with a value greater than 0 for the Number of Neighbors parameter.
