Phil Steitz updated MATH-228: ----------------------------- Fix Version/s: (was: 2.2) 3.0 Still struggling with the distribution, so moving out to 3.0 > Feature request for one and two sample Kolmogorov-Smirnov test as well as > Lilliefors test > ----------------------------------------------------------------------------------------- > > Key: MATH-228 > URL: https://issues.apache.org/jira/browse/MATH-228 > Project: Commons Math > Issue Type: New Feature > Affects Versions: 1.2 > Environment: All > Reporter: Anirban Basu > Priority: Minor > Fix For: 3.0 > > Original Estimate: 336h > Remaining Estimate: 336h > > It would be very helpful to have implementations of one and two sample > [Kolmogorov-Smirnov > test|http://en.wikipedia.org/wiki/Kolmogorov-Smirnov_test] as well as > [Lilliefors test|http://en.wikipedia.org/wiki/Lilliefors_test] with > MATLAB-style results in future versions of Commons Math. > For example, Lilliefors test on sample data: > sampleVector = [0.0033413022337048857, 0.008527692135731013, > -0.004902763950955454, 0.033018433100296396, -0.020495504044139023, > 0.003978726052913162, 0.003847972673931109, 0.009160477945515444, > -0.011113437653216639, -0.01164235145079795, 0.017180306607011864, > -0.01818483009998717, -0.010479811709006803, -0.033991339307749, > -0.007057160031600951, -1.2398497120424956E-4, 0.0026913151777877564, > 0.03580425341677764, -0.006404370278251359, 0.007579083257585828, > -0.005912037207256193, 0.01241830354576745, -0.0012524631744377235, > -0.005900927958040758, 0.0028847985848513558, 0.005313417226899042, > 0.018923743379700153, 0.010976836172447269, -0.017847220928846164, > 0.0024067380689056783, -0.011912393656503872, -0.019985462687391875, > 0.017318878212931876, 0.003592873590795409, -0.00332615776078915, > -0.018222673013956525, -0.021591768336351125]; > [h, p] = lillietest(sampleVector) > Warning: P is greater than the largest tabulated value, returning 0.5. > > In lillietest at 166 > h = > 0 > p = > 0.5000 > This uses Lilliefors test for normality.
