   Hi all,
   
   In the second term of the sigma^2 expression in the examiner report i.e specifically for y_1, why does this not contain "1/n"?
   
   In page 40 of the yellow book, the formula for y_k does contain "1/n" so I'm not sure why this is not included here.
   
   Thanks!

   Hi Laura
   
   Looks like a typo in the Examiners' report to me. I believe there should be the 1/n in the second term.
   
   All the best
