Webb7 nov. 2024 · The Shapiro-Wilk test is a hypothesis test that is applied to a sample and whose null hypothesis is that the sample has been generated from a normal distribution. If the p-value is low, we can reject such a null hypothesis and say that the sample has not been generated from a normal distribution. Webbtest, Cramer-von Mises test, Shapiro-Wilk test and Shapiro-Francia test. The first three tests are. based on the empirical cumulative distribution.
