comment Deriving an equation
@Did: I am correct. I think I just copied the question incorrectly which was incorrect by the original post. "The first equation simplified" was wrong.

@Did: I used the identity $\log_{b} (x) - \log_{b}(y) = \log_{b} \frac{x}{y}$.

@Did: I was using the fact that $\sum_{x} p(x,y) = p(y)$. Then $\sum_{x} p(x,y) \log_{2} p(x,y) = p(y) \log_{2} p(y)$.

comment Conditional Distributions and Probabilities
@Greg: Since we are given the distribution $\epsilon| \eta \sim N(\rho \eta, \sigma^2)$, I don't think we need the extra $\frac{1}{\sigma}$.
