Correction to lecture note 4 and posted message on SER_澳门葡京手机版app下载

I mistakenly wrote that rMSE=sqrt(SER) in my previous Message, however the correct thing is that rMSE=SER.

This comes from there being a typo in lecture note 4 slide 29, where it says that SER=\sigma^2. The correct SER is in lecture note 8 slide 13, or Equation 6.13 in S&W.

I am sorry for any confusion this must have created.
