Webb21 maj 2024 · The two most known tests to check the normality assumption are the Shapiro-Wilk test and the Kolmogorov-Smirnov test. Both test the null hypothesis that a set of observations (e.g., the residuals) do follow a normal distribution. By rejecting this null hypothesis we can assume that the residuals are not normally distributed. WebbThe power of each test was then obtained by comparing the normality test statistics with the respective critical values. Results show that the power of all six tests is low for small sample size(see, for example [2]). But for n = 20, the Shapiro-Wilk test and Anderson - Darling test have achieved high power.
