This function tests the null hypothesis that a sample comes from a normal distribution. It is based on D’Agostino and Pearson’s [1], [2] test that combines skew and kurtosis to produce an omnibus test of normality. Parameters: aarray_like The array containing the sample to be tested. crafts \u0026 drafts nc
