Hello , I want to ask about davies boulden's results and avg. within centroid distance's results, I did a cluster with k-mean with loop of k start from 2 to 25, so I use davies boulden and avg. within centroid distance to evaluate results, so the final result shows that davies boulden is infinity and avg. within centroid distance is zero when k = 4 and above , so I what I need to do ? remove results from k and above or there is an error and I can fix it?
