The Anderson-Darling normality test is a statistical test used to determine if a given dataset follows a normal distribution. It measures the discrepancy between the observed data and the expected values under the assumption of normality. The test yields a test statistic value, referred to as the Anderson-Darling statistic, which provides insight into the goodness-of-fit of the data to a normal distribution. A higher test statistic value indicates a greater deviation from normality.<\/p>\n
