hi
after using ADF test & zivot andrew test i found that:
in ADF test, price was stationary in intercept while the other 2 models ( just trend, intercept and trend) were non stationary, alos the dlog(price) was sationary in all 3 vesion as expected.
in zivot-andrews both daily price and return of stock market were stationary in all 3 versions
how can I infer them?
