How to implement Cramer's test in Java? - Cramer - 'ArrayStoreException' about moa HOT 4 CLOSED

I guess the two samples Cramer test is the Anderson-Darling-Test?

@pmgj: can you help on this? Thanks!

Hi,

This cramer test works comparing the attribute values of a List of Instance elements. An example that can read values from ARFF files is:

    List<Instance> x = Cramer.fileToInstances("test1-x.arff");
    List<Instance> y = Cramer.fileToInstances("test1-y.arff");
    Cramer c = new Cramer();
    Cramer.CramerTest ct = c.cramerTest(x, y);
    System.out.println("p Value.: " + ct.pValue);
    System.out.println("Critical value: " + ct.critValue);
    System.out.println("Statistic: " + ct.statistic);

The CramerTest is only used inside the class. I probably had to make it private. This Java implementation was based on the Cramer test source code available in the R statistic tool.

Thanks a lot.
