Hi everyone,
I found your website and have recently started using GRETL. I am running
time series>Cointegration Test>Engle-Granger.
Now for the u^hat of the cointegration regression in Step 4
I would like to tell GRETL to PLOT these residuals for me.
Then I want to calculate standard deviation bands around the zero line and also plot these on the u^hat residual plot chart.
A 3x standard deviation horizontal line for positive residuals and the same for negative residuals.
Can this be done? I would greatly appreciate feedback.
Regards,
