# k-means

hello

I have 3 questions respect to clustering:

1. I want to see the plot of clustering and i want to see the image of clusters. i can't see this in plot view after clustering

2. after i do clustering with k-means, i see this: "Avg. within centroid distance: -2.022" why this is negative?

3. k=15 then Avg. within centroid distance:-2.657 and Davies Bouldin: -1.086 or when k=20 then Avg. within centroid distance: -2.346 and Davies Bouldin: -1.273 and so on. isn't problem and what is the meaning?

I really appreciate your help!

The distance has a negative sign due to internal reasons. It should be fixed in one of the next versions. Until then you can safely ignore the sign - the absolute value is correct in any case.

I don't understand your 3rd question - can you explain your problem a bit more detailed?
