Hi, I have a question when working on cluster analysis.
How can I draw an Elbow Evaluation plot in determining the best number of clusters? Thanks!
proc fastclus
data=HOTEL_EMEA
maxc=10
maxiter=10
out=clust;
var avg_pct;
run;
use proc princomp to get two primary component of your data. And plot them at X-Y axis .you can see the number of cluster you should split.
Here is an example:

I would do Primary Component Analysis and get those two PC and polt them by proc sgplot ,and you could probably get N of clusters.
Ksharp,
Could you please give me one simple example? What do you mean by 'get those two PC' in your reply?

Cool!
Can we cluster analysis only with continous varaibles?
