Hi rooters, given two columns of numbers, x[i] and y[i] (stored, for instance, in a TGraph) I would like to know the correlation between the two variables. Is there an easy way to do that in ROOT? I couldn't find anything appropriate. There is a method GetCorrelationFactor in TH2, but if possible I don't want to bin my data.
