> I'm using the kolmogovSmirnovTest method to calculate pvalues.
> However, when i try running the test on two double[] of sizes 5 and 45 the results take over 10 seconds to calculate.
> This seems very long, whereas in R it takes a few miliseconds for the same calculation.
> I'd be very happy to hear any comment you may have on the subject.
