Three notes:
1. Shapiro test is for testing a sample size under 2000. For a large sample
size which is over 2000, Kolmogorov test should be used instead.
2. Test statistic alone may not be sufficient. To test normality, it is
recommended to use normality probability plot, too.
3. Shapiro test is for testing univariate normality. For multivariate
normality, use Q-Q plots and some other tests.
Hope it helps.
