> I have code simplified to the following:
> KolmogorovSmirnovTest kst = new KolmogorovSmirnovTest();
> NormalDistribution nd = new NormalDistribution(mean,stddev);
> kst.kolmogorovSmirnovTest(nd,dataset)
> I find that for my dataset of 10,000 items, the call to kolmogorovSmirnovTest
> takes 'forever'. It has not returned after nearly 15minutes and in one my my
> tests has gone over 150MB in memory usage.
