Engle Granger Vs adf test on residuals
Posted: Tue Jul 05, 2016 12:58 am
Hi everyone, this is my very first post, so in case of any mistake i apologize in advance.
This is my problem: i was making some analysis on a currency pairs in order to develop a pairs trading strategy. I was pretty sure about the fact that the following two procedures were the same:
1)make a two step engle granger test by click ing the eviews test
2) i personally made the ols equation of the two currencies and once saved the residuals, I made the adf test on these.
However my results lead to two opposite directions: the first procedure shows no cointegration while the second show stationarity of residuals. Doesn't it mean they are cointegrated?
