I'm performing an analysis of the log GDP of Switzerland using eViews and I have to do an ADF-Test to check wheter the series is stationary or not. From the graph, I'll say that the series is not stationary but rather follows an upwarding trend, would you say that too?
My question is: when I do the ADF test, for this case, should I include both trend and intercept? Or what? Because if I incloude both trend and intercept, these are the results that I've got:
So they instead say that the series is STATIONARY, right? we have sufficiently proof to reject the NH! Is it "trend stationary" though?
Please, be patient is my very first attempt at econometrics! Thank you
