Shapiro wilk equation
WebbThe Shapiro–Wilk test was used to assess normality of distributions in the gathered measurements, and according to the results we applied parametric (Welch’s t test ) or non-parametric (Wilcoxon rank sum test [71,72]) methods where suitable to compare differences in performance between real-3D and pseudo-3D conditions.

The Shapiro–Wilk test tests the null hypothesis that a sample x 1, ..., x n came from a normally distributed population. The test statistic is W = ( ∑ i = 1 n a i x ( i ) ) 2 ∑ i = 1 n ( x i − x ¯ ) 2 , {\displaystyle W={\left(\sum _{i=1}^{n}a_{i}x_{(i)}\right)^{2} \over \sum _{i=1}^{n}(x_{i}-{\overline {x}})^{2}},} 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 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 • Anderson–Darling test • Cramér–von Mises criterion • D'Agostino's K-squared test • Kolmogorov–Smirnov test • Lilliefors 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 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.
