 +  * **Maximum iterations**: How many times the calculations will be run, more iterations will refine the results at the cost of longer processing times. 
 +  * **Determine Number of PCs Using Variance Explained**: Can be used to determine the number of PCs (i.e. dimensionality) of the K-Means test using variance explained instead of number of PCs

 +  * **Scale PC Scores to Variance Explained**: Normalizes the scale on the workspace scores using the variance explained. 
 +  * **Switch Display Style to by Cluster**: Automatically changes the display style to cluster, after running a K-Means Test. 
 +  * **Use Custom Seed For First Centroid**: Allows the selection of a custom seed instead of a randomly generated one, creates consistent results across runs.
