Monte Carlo simulation has found that Shapiro–Wilk has the best power for a given significance, followed closely by Anderson–Darling when comparing the Shapiro–Wilk, Kolmogorov–Smirnov, and Lilliefors. Visa mer The Shapiro–Wilk test is a test of normality. It was published in 1965 by Samuel Sanford Shapiro and Martin Wilk. Visa mer Royston proposed an alternative method of calculating the coefficients vector by providing an algorithm for calculating values that extended the sample size from 50 to 2,000. This … Visa mer • Worked example using Excel • Algorithm AS R94 (Shapiro Wilk) FORTRAN code • Exploratory analysis using the Shapiro–Wilk normality test in R • Real Statistics Using Excel: the Shapiro-Wilk Expanded Test Visa mer The null-hypothesis of this test is that the population is normally distributed. Thus, if the p value is less than the chosen alpha level, then the null hypothesis is rejected and there is evidence that the data tested are not normally distributed. On the other hand, if the p value is … Visa mer • Anderson–Darling test • Cramér–von Mises criterion • D'Agostino's K-squared test Visa mer WebbThe Shapiro-Wilk test examines if a variable is normally distributed in some population.
