Thank you, Mr. Chair.
And thank you, witnesses, for appearing before us again. This has certainly been an interesting day, and I think we all have a lot to ponder.
I want to reflect and I want to just carry on with the question that I think was asked by Mr. Stanton. We were talking about putting into effect what I believe our analyst called the Granger causality tests. Do we have statistical evidence? Have we used that to determine whether or not this correlation actually exists between spot price and futures in crude? Have we applied that test to this?
