Dickey-fuller test for unit root
http://www.ams.sunysb.edu/~zhu/ams586/UnitRoot_ADF.pdf WebEngle Granger Test. The Engle Granger test is a test for cointegration. It constructs residuals (errors) based on the static regression. The test uses the residuals to see if unit roots are present, using Augmented Dickey-Fuller test or another, similar test. The residuals will be practically stationary if the time series is cointegrated.
