Unit root was one of the most obscure concept I have ever met. Thanks to you and a couple of other dudes online I reached a sufficient level of comprehension. Thank you!

Hello, Justin. Excellent video. Could you explain the relation between unit root and eigenvalues of a matrix?

hello can i ask something. i used r studio with adf.test and kpss.test with "level" as specification. what does it mean if the results are contradictory? the adf.test shows that my series have no unit roots however the kpss.test shows that my series are not stationary?
