Thank you for all the answers! Kjetil, I am not sure if we are talking about the same thing. I only have a two dimensional normal distribution which leads to three dimensional data. You mean with "reject" I should not do such a test? My data files contain about 26 points which I can reduce

This is probably an even more basic question but shapiro.test return both the statistic (w) and the significance (pw) of the statistic. For this test the null-hypothesis is that the distirbution is not normal so very small values of pw would mean that there is very little chance that the distiri

Hi all, I am completely new to R and my knowledge of statistics is quite small so I hope you can help my. I have three dimensional point data which represents (and this is what I do not know for sure) a normal distribution. Now I want to test if this is true or not and as I can remember from s
