Where is the hierarchical clustering?

[Atabarezz]

Is there a reason why Alteryx does not include hierarchical clustering?

Well it's sort of slow especially with huge data sets, computation effort increases cubic, but then when you need to do two step clustering,

"creating more than enough k-means clusters and joining cluster centers with hierarchical clustering" it seems to be a must...

P.s. Knime, SPSS modeler, SAS, Rapidminer has it already...

Just bumped into this now, while doing the second-last assignment on the Udacity Nano-degree.    Not sure if anyone responded to you on this @Atabarezz or if this is a genuine gap in the product?

[Atabarezz]

No response at all... Thanks for paying attention Sean.

This method is available as an R package but not as a tool in Alteryx...

When this method is used in conjunction with K-means clustering tool

Alteryx will become an even more powerful tool providing more accurate segmentation

Here is a nice blog post from analytics vidhya explaining k-means (available in Alteryx)

vs. hierarchical clustering (not available in Alteryx);

By the way if you combine two methods;

• a very detailed (high number of K's) K-means or medoids model (which is always a fast algorithm)
• with a hierarchical model (normally it's slow with big data but for a managable number of K-means clusters it's fast as well)

you basically get a two-step clustering algorithm that already exists in SPSS Modeller...

I would love to see a tool for this

It will good to have hierarchical clustering in Alteryx with the standard clustering methods including Ward's.
