Hi Michael,
there are basically two different ways to use the ChiSquare test:
* compute the chi-square test of independence (use the
chiSquareTest(long[][]) method)

chiSquareTest(double[], long[]) method)
In your example, you computed the

Hi Thorsten,
this sounds like a very specific use-case of a hierarchical clustering.
I could imagine the following way to achieve it:
* first cluster all data points with kmeans, with a k=50 as you would like
to have 50 clusters on level 2
* take the 50 clusters and feed them into a HAC like
* v constraint and everything is alright.
