Hi all,

I have a dataset of 2000 numbers ( it's noise measured with a scoop )

Now i want to know of my data is normal distributed (Gaussian distribution).

I did already:

- 68-95-99.7 test
- Q-Q-plot

and now i used "nortest library" and the Lilli.test()

However i don't understad the output?

lillie.test(z)

	Lilliefors (Kolmogorov-Smirnov) normality test

data:  z 
D = 0.0218, p-value = 0.0278

I read wiki, but still can understand it..

Can anyone, give an explanation of my output D and p-value?

Thanks in advance

Gr. Bosken
