Hello,

 

I am using the Clustering in VA. When I derive Cluster IDs, I see -1 as the output of the derived variables. What does -1 mean? Thanks!

I believe it means that there are missing values for some of the observations.

I was thinking about the outliers but it is just a guess... I couldn't find any documentation either. Thanks for the reply!
