Web21 Oct 2013 · scipy.stats.normaltest¶ scipy.stats.normaltest(a, axis=0) [source] ¶ Tests whether a sample differs from a normal distribution. This function tests the null hypothesis that a sample comes from a normal distribution. It is based on D’Agostino and Pearson’s , test that combines skew and kurtosis to produce an omnibus test of normality. Web9 Nov 2024 · test of normality A normal distribution is one of the most famous statistics distributions and it is informally called bell curve shape. Normal distributions are important in statistics and are often used in the natural and social sciences to represent real-valued random variables whose distributions are not known.
