PerformKSNormalityTest


Unit:SDL_statis
Class: none
Declaration: function PerformKSNormalityTest (Data: TVector; IsSorted: boolean): double;

The function PerformKSNormalityTest performs a test for normality according to Kolmogorov and Smirnov. The data to be tested is contained in the vector Data. The parameter IsSorted should be set to TRUE if the values in Data are already sorted in ascending order (this speeds up calculation for long data vectors).

Please note that the KS-test compares the data to be tested to the standard normal distribution (with mean=0.0 and std.dev.=1.0). If you want to test for a normal distribution of any mean or standard deviation you should use Lilliefors' test (function PerformLillieforsTest).

Hint: The routine PerformKSNormalityTest changes the data vector if IsSorted is set to FALSE.
