Clustering

Hello

1) I am getting warning about correlated variables as shown in the screenshot, is there any specific reason for this?.

2) How to profile and interpret clusters when an interaction variable is used.

Thanks

What do I do when confronted with a mysterious warning or error? Search on the text.

Googling "warning: the two values above are invalid for correlated variables" yields:

and

among others. The internet can be a rich resource, use it.

How an analyst can decide which of the following method in Heirarchical clustering to be used in which scenario.

Single Linkage, Complete linkage, centroid linkage.
