<br><b>Min Threshold</b><br>
Specifies the minimum sample threshold.  The number of samples 
in a cluster domain is compared to Min Threshold in the following way:
 
When the number of samples in a cluster is less than the Min Threshold,
the cluster will be discarded and the total number of clusters
will be reduced by 1.  
 
For a cluster,
<P>
<UL>
<LI> if the standard deviation is greater than the Standard Deviation, AND
<LI> if the average distance of samples from the cluster center 
is greater than the overall average distance of the samples
from their respective cluster centers, AND 
<LI> if the total number of clusters is less than Max Clusters, AND
<LI> if the number of samples in the cluster is greater than 
2(Min Threshold+1), OR
<LI> if the number of clusters is less than or equal to Desired Clusters/2,
</UL>
then splitting of the cluster will occur.
