Hi,


I try to implement O-Cluster algorithm.


In one of its step I have to choose where the data should be split. I
calculate histogram and try to find valley surrounded by two peaks. The
difference between peak and the valley histogram counts is checked using
Chi-square statistical test whether it is statistical significance.
Thats all :)
