The requirement is close to usual. The take a look at won't be able to inform you that. Exams also get extremely sensitive at significant N's or even more significantly, differ in sensitivity with N. Your N is in that range where by sensitivity commences receiving large. If you operate the subsequent simulation in R numerous website instances and look at the plots then you will see the normality check is saying "not regular" on a good amount of standard distributions.
. The only real scenario I'm able to think of off the best of my head wherever centering is useful is in advance of generating energy terms.
