Hello,
What is the suitable normality test for 20000 data ?
Best regards

Can you tell us what the data is and what kinds of analyses you want to do? It may or may not be important to make an assumption of normality.

Are you expecting A Gausian normal distribution?

Try jarque.bera.test(x) from the {tseries} package.

But also think about @jrkrideau's questions. With 20,000 observations you may well reject normality even if the deviation is trivial.
