Hi Guys

I have a sample of N iid normal distributed variables. And I need to calculate the Variance of the Maximumlikelihood estimated variance (sample variance)

Can somebody help me. I just can't come to an answer

Cheers

Hello,

This rv follows a distribution :D So if you look at a table you should get its variance :p - May 12th 2010, 11:14 PMmatheagle
Nope, the sum over has a chi-square distribution.

Hence
