Hi everybody,

somehow i dont get the shapiro wilk test for normality. i just canīt find what the H0 is .

i tried :

  shapiro.test(rnorm(5000))

        Shapiro-Wilk normality test

data: rnorm(5000)
W = 0.9997, p-value = 0.6205

If normality is the H0, the test says itīs probably not normal, doesn īt it ?

5000 is the biggest n allowed by the test...

are there any other test ? ( i know qqnorm already ;)

thanks in advance

matthias
