Christmas Challenge

This is just for fun and to win a real prize you need to have been very good all year and have a generous expense account.

Good old Santa wants to give you a Christmas present. He’s checked if you have been naughty or nice and the news is not good, so you have to pick the right present. One of the presents holds the all expenses-paid trip to iSixSigma Live (Miami - January 13-16) the other two presents hold copies of that classic text Statistical Analysis of Cointegration Vectors.

But Santa is a kind fellow and knowing you are a statistician decides to give you a choice. He asks which present you have picked, maybe it was B. He looks thoughtfully and tells you the prize is definitely not present A, would you like to change your mind? What will you do? Click the link to see how you do.

• No thanks Santa, I’ll stick with what I picked
• Thank you Santa, I’ll change my mind

Wishing you all a Merry Christmas and a Happy New Year!
