Cluster tables

Constrained clustering produces two types of cluster data tables—one of just the spatial locations and their cluster assignments (type "Data"), and a second that provides information by cluster on the values of the data from locations within each cluster (type "Cluster Statistics"). The descriptive statistics file contains information on each cluster, such as the number of elements in each cluster and the cluster's mean and variance for each variable.

Data are generally standardized prior to clustering. If you chose to standardize the data prior to clustering, the Clusters data set will display the standardized data. If you wish to see which standardization method you chose, consult the project log.

To view these tables, go to the "Project menu" and choose "Table." Scroll down until you see the tables you require. Alternatively, right-click on the Clusters file in the Data tab of the Project Window. Choose "View Table" and then choose to view either "Data" or "Descriptive Statistics."

If you wish to export the boundaries for use in another program, they will be exported in shapefile format (*.shp, *.shx, and *.dbf) with the mean for each of the variables you used to detect boundaries.
