I'm also interested in this, having tried and semi-successfully used mutual information for finding associations between multinomial variables. As an even more naive question, I find the actual selection of estimators bewildering. How do I know which estimator to use for mutual information? How do I know if my chosen estimator has converged or is doing a bad job on my data? Bringing it back to the topic at hand, does the estimator presented in the paper provide good estimates for a wider variety of cases than the mutual information plug-in estimator? If so I can see it might be nice for simplicity reasons alone. Can we have different estimators for this new correlation coefficient? Any ideas what that would look like?
