Jan 23, 2021 · I think your final answer should be x'y + xz + yz, if you introduce xx' which evaluates to zero, you will be able to get to the final answer. Nevertheless, please find the complete solution: Expanding the above: x'y + yz + x'x + xz => x'y + yz + xz which is equal to above. Hope this has answered your question.
But $E(E(Y\mid X,Z)\mid Z)=E(Y\mid Z)$ is always true (and is often called the tower property). What I proved in my post uses another property, which is that $E(U\mid V)=U$ as soon as $U$ is $\sigma(V)$-measurable. $\endgroup$
Dec 1, 2016 · Indeed, for a given value $y$, $\mathbb{E}(X|Y=y)$ is a constant for which taking a conditional expectation conditional on the realisation $Z=z$ makes little sense as it also returns $\mathbb{E}(X|Y=y)$.

$E(X|Y)$ is the expectation of a random variable: the expectation of $X$ conditional on $Y$. $E(X|Y=y)$, on the other hand, is a particular value: the expected value of $X$ when $Y=y$.
