Hi all, I've recently installed this library to help me with some basic statistics in my project. I wanted to calculate the correlation coefficient for 2 arrays, which I see I can do with "PearsonsCorrelation". However, I realized that I should be using a special variant of Pearson if one of the variables is nominal - Point Biserial correlation coefficient. Could you tell me if this is somehow supported in the library and if not, if there is a similar Java library which can calculate the Point Biserial coefficient. Thanks for your help!
