Phillips-Ouliaris Cointegration Test

In this short tutorial in Eviews, we would explain the basic steps of conduting Phillips-Ouliaris Cointegration Test. To run Phillips-Ouliaris Cointegration Test in Eviews, we will need to ender the data as dated frequency and panel structure. Theoretically, the Phillips-Ouliaris Cointegration Test can found well explained in P. C. B. Phillips and S. Ouliaris (1990): Asymptotic Properties of Residual Based Tests for Cointegration. Econometrica 58, 165–193 which can be downloaded here.

Phillips-Ouliaris Cointegration Test

To run Phillips-Ouliaris Cointegration Test in Eviews, open Eviews and follow the steps below:

The following video tutorial explains the above steps to help replication be more convenient. If you would like to learn more about Applied Econometrics Research using Eviews, check our private and instructor led courses here.

ARDL and Unit Root Testing using Eviews

ARDL Cointegration using Eviews 9

To estimate ARDL using Eviews 9 on Time Series Data, first open the data file/workfile, Click on your DV, press control key on keyboard, now left click to select all your IVs one by one, once selected then right click on any selected variables and open these as Equations. Once you get the Methods window in Eviews, go the methodology selection from Estimation Setting near to bottom, select ARDL from the list and click Okay. Now you cans elect the lags of DV and IV and any other options for the the methods. You can click on the OK button to get your estimates.

Augmented Dickey Fuller Unit Root Test using Eviews

Augmented Dickey Fuller Unit Root Test using Eviews We can test a time series variable for Unit Root Test following Augmented Dickey Fuller Approach in Eviews following the steps outlined below. First of all open the Eviews workfile or the Excel data in Eviews, then right click on any of the variables we would like to test for unit root based on Augmented Dickey Fuller Approach and click on Open. The series opens in spreadsheet in Eviews. We can click on View in the left upper corner of the new spreadsheet window in Eviews. Then we can click on Unit Root Test in this list that pops down by clicking on View tab. This opens the dialogue box as shown in the inserted screenshot from Eviews itself, we can see that it has mainly four sections. Main section is related to selecting the test type. The Eviews produces unit root test results following 6 methods. We will select the Augmented Dickey Fuller as test type. The we will select either the Level, Difference or Second Difference. Next we can select either to include intercept or both of trend and intercept or none. On the right side of the same window, we can either ask Eviews to use lags automatically or we can insert manually the maximum lags into the model to base our unit root test on. Once we select everything as per our assumed approach to test a series for unit root using Augmented Dickey Fuller Approach, we can click on OK to get the test results.
