Hi Phil I took a closer look at the Spearmans correlation and note that it uses an underlying PearsonsCorrelation object to do the actual work of calculating the correlation value after ranking. Do I have to do the same for Kendalls Tau? I.e. Do I need to have two classes 1)KendallsTauCorrelatio

Hi Phil and All. Thanks for the welcome. I manage to get,build and test the SVN trunk branch and took a look at the Spearmans Rank implementation. I did notice a few test failures overall in the build such as RealVectorTest, hopefully they are part of the build and not something I am missing in my

Hi All, Below is a proposal for a new feature: *A concise description of the new feature / enhancement* * * I propose a new feature to implement the Kendall's Tau which is a measure of Association/Correlation between ranked ordinal data. *References to definitions and algorithms.* * *A basic des
