When performing the test, the W statistic is only positive and represents the difference between the estimated model and the observations. The bigger the statistic, the more likely the model is not correct.

WebbNormality Tests Four commonly used tests of normality can be performed; Shapiro-Wilk, Kolmogorov-Smirnov, Cramer-von Mises and Anderson-Darling. The test statistics are displayed with their probability values and optionally, with basic sample statistics (number of cases, mean and standard deviation).
