Errata

I found some minor errors in the second part of the last entry. The corrections are given below.


The errors didn't affect the main result. The uncertainty in σ^2 is σ^2/n and there was an error in the sign of δθ which would account for some lack of confidence in what I had done. Notice that all the components of δCov' now have the units of length squared and that δθ is unitless.
