Coskew

[afterworkguinness]

Hello,
I'm lost with the calculations in the notes for coskewness, I understand conceptually what coskewness is though. In your opinion, should I spend time to understand ? Thanks

Hi afterwork,

To pass the exam in 2013, no, I do not think you need to go beyond conceptual understanding. The new AIM is appropriately conceptual not quantitative:
"Interpret the skewness and kurtosis of a statistical distribution, and interpret the concepts of coskewness and cokurtosis"

My notebook entry might be helpful http://forum.bionicturtle.com/threads/coskew-and-cokurtosis-in-miller-chapter-3-p1-frm.6808/
... IMO, you almost need the XLS to comprehend, we will publish the associated learning XLS out soon, but it's academic really (not necessary for exam)
