"some questions about hierarchical clustering"
When does this happen and what might be wrong with my model or data? (see below for related information)
2. When i export the model to an XML file (with the Write operator) I see a number of "distance" tags. They encapsulate numeric values which seem to be the cluster distances and they all are either 0.0 or a negative number (preceded with "-"). Is this the cluster distance? And if this is the case, what would make the distance be negative? I am using the Jaccard distance to generate the model
3. The flatten operator seems useful to get a simple list of some clusters. Is it possible to obtain the distance for each of the clusters in the output of the flatten operator?
Thanks for the help, in advance.
