Webb(See the output of the proc univariate above.) In the Shapiro-Wilk W test for normality, the p-value is based on the assumption that the distribution is normal. In our example, the p-value is very large (0.51), indicating that we cannot reject that r is normally distributed. (See the output of the proc univariate above.) 2.3 Tests for ...
