Thank you @P_Bartell .

From the "art" category, I suspect it is non-stationary so I would like to confirm through some statistical test like ADF test (looking for a p-value).

I've checked the Time Series platform in JMP, but it didn't show p-value for ADF test.

Not sure what does Zero Mean ADF/Single Mean/Trend ADF.

I guess, I have to do it in R/R-Studio.

Thanks anyway !
