20 Feb 2013 Discretization algorithms: Class-Attribute Contingency Coefficient To discrete continuous data, CACC is a promising discretization scheme proposed in 2008 Author: Guangdi Li

This implementation is not complete and it is actually incorrect, for starters the CACC is not computed. This code obtains y' and takes that as the CACC (which is obviously wrong). And the algorithm is not implemented in full as described in the paper.

That is why people that tries this code with the data from the paper obtain different results.

People please check my (hopefully correct) implementation and let me know about any bugs.

You are the best, Guangdi!

Hello Guangdi, there seems to be a bug on this function, if you try, for example, with these two vectors, the function enters into an infinite loop:

X = [1,1,1,1,1,1,1,1,1,1,1,1,1,0,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,2,1,1,2,1,2,1,2,1,1,1,1,1,1,1,2,2,1,1,1,2,1,1,2,1,1,1,2,2,2,1,1,1,2,1,1,1,1,1,1,1,1,1,1,1,1,1,1];

Y = [1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,0,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,2,1,2,2,2,2,1,2,2,2,1,2,2,1,1,2,2,2,2,1,2,1,2,1,2,2,1,1,2,2,2,2,2,1,2,2,2,2,1,2,2,1,1,2,2,2,1,2,2,1];
