Bug Description

i'm currently evaluating JASP versus Minitab.
one of the basic test is normality test, on my dataset with Minitab i have a p-value of 0.072 using Anderson-Darling test.
doing it with JASP, using same anderson-Darling test i have a p-value of 0.558 which is very very different...
here is the dataset i'm using:

Expected Behaviour

i should have an anderson-darling p-value of #0.07

Steps to Reproduce

1.copy paste the data i provided
2.launch distribution / normal function
3.select the proper dataset
4.select anderson darling in Asses-Fit/statistics

Final Checklist

• I have included a screenshot showcasing the issue, if possible.
• I have included a JASP file (zipped) or data file that causes the crash/bug, if applicable.
• I have accurately described the bug, and steps to reproduce it.

Yes, I have these results:

The Shapiro-Wilk does give a much lower p-value. I will now check this with R...

library(nortest)
ad.test(x)
This yields
Anderson-Darling normality test
data: x
A = 0.68448, p-value = 0.0717
@Kucharssim do you know what is going on?
Now that we are at it:

lillie.test(x)

    Lilliefors (Kolmogorov-Smirnov) normality test

data: x
D = 0.077633, p-value = 0.1456
@simon, the p-value here is also different

cvm.test(x)

    Cramer-von Mises normality test

data: x
W = 0.11275, p-value = 0.07396
@simon, the p-value is again different.

sf.test(x)

    Shapiro-Francia normality test

data: x
W = 0.97997, p-value = 0.1176

I am not sure what's going on.

If this is really a bug (it certainly seems so right now) it needs to be fixed relatively soon. For me it is on the borderline of a hotfix, and it would certainly need to be mentioned under "known issues". Let's get to the bottom of this soon! (I have trouble understanding how this error could have crept in; is it a malfunctioning R package?!)
