-1 cluster node

Posted 03-12-2024 11:50 AM (454 views)

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!
