WebbEn estadística, la prueba de Shapiro–Wilk se usa para contrastar la normalidad de un conjunto de datos. Se plantea como hipótesis nula que una muestra proviene de una … The Shapiro–Wilk test is a test of normality. It was published in 1965 by Samuel Sanford Shapiro and Martin Wilk. 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 … Visa mer 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 • 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 Royston proposed an alternative method of calculating the coefficients vector by providing an algorithm for calculating values that extended … Visa mer • Anderson–Darling test • Cramér–von Mises criterion • D'Agostino's K-squared test Visa mer sharee fallon mount
