ClusterDistance value

DanMeyers

Can somebody please define the result of the ClusterDistance() function for me.  BOL and MSDN are vague about what the output means and I am getting some cases that have a value of zero and sometimes there are more than one per cluster. 

Thanks in advance,

Dan Meyers

I believe the clusterdistance() is simply 1-clusterprobability(). Are you saying you are getting more that one "0" value of cluster distance for different clusters on a single case

DanMeyers

No.  I am getting more than one case per cluster that has a ClusterDistance() value of "0".

Jamie MacLennan

That's ok - it's an issue if you get more than one cluster per case with a ClusterDistance() of 0. Imagine if you have two identical cases - it would make sense that they have the same ClusterDistance(), would it not

DanMeyers

It does make sense. I just wanted to make sure that I was understanding everything correctly and I was not sure because the documentation is a bit vague in its definition of the function.

Thanks Jamie.
