evolution of variance!

Hi All, I was unable to post the contents here…got an error message…perhaps due to lots of brackets for notation, etc. I had to create a site just so that I can post it and let you guys comment on it: http://cfa-level-1.blogspot.com/ Sorry about the link - but I had no choice… Appreciate any comments you guys can provide. Cheers


I think you have covered most there. But the best way to check and retain is by taking more and more questions. Best of luck.
