Chen Tao commented on MATH-1487:
--------------------------------
I can not reproduce this bug both in 3.6.1 and development version, by this
code:
@Testpublic void testCase() throws IOException { double[] alpha =
readToDoubleArray("alpha.arr"); double[] beta = readToDoubleArray("beta.arr");
KolmogorovSmirnovTest kolmogorovSmirnovTest = new KolmogorovSmirnovTest();
kolmogorovSmirnovTest.kolmogorovSmirnovTest(alpha, beta);
}private double[] readToDoubleArray(final String filename) throws IOException {
return Files.readAllLines(Paths.get("path", "to", "arrays", filename))
.stream()
.mapToDouble(Double::parseDouble)
.toArray();
}
More information should be provide.
