WebBut this takes away one degree of freedom (if you know the sample mean, then only ξi from 1 to n − 1 can take arbitrary values, but the n th has to be ξn = ˆξ − n − 1 ∑ i = 1ξi ). So your real S2 loses one degree of freedom: ( n − 1) S2 σ2 = n ∑ i = 1(ξi − ˉξ σ)2 ∼ χ2n − 1. Oh, and here's a cute kitten for you.
