K-Means Dialog
The K-Means button is found on the toolbar and under 
Outlier Detection.
- Number of Clusters: The number of clusters to be calculated.
- Maximum iterations: How many times the calculations will be run, more iterations will refine the results at the cost of longer processing times.
- Run Cumulative Variance Model: Can be used to determine the range of the K-Means test using variance explained instead of number of PCs
- Number of PCs (1-25): The number of principal components representing the workspace.
- Scale PC Scores to Variance Explained: Normalizes the scale on the workspace scores using the variance explained
- Use Custom Seed For First Centroid: Allows the selection of a custom seed instead of a randomly generated one, creates consistent results across runs.
