The test statistic is. where. x ( i ) {\displaystyle x_ { (i)}} with parentheses enclosing the subscript index i is the i th order statistic, i.e., the i th-smallest number in the sample (not to be confused with. x i ... Ver mais The Shapiro–Wilk test is a test of normality. It was published in 1965 by Samuel Sanford Shapiro and Martin Wilk. Ver mais 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, Ver mais • Anderson–Darling test • Cramér–von Mises criterion • D'Agostino's K-squared test Ver mais 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 … Ver mais 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.

One common property, upon which many linear tests depend, is that of normality — the data must have been drawn from a normal distribution.
