Prove the law of iterated expectation
Webb11 aug. 2024 · The law of iterated expectations, sometimes called the law of total expectation, tells us that. E ( Y) = E ( E ( Y ∣ X)). So we look at E ( Y ∣ X) : E ( Y ∣ X) = { 1 / 2 …

I provide the basic statement of the law and then illustrate how it applies to some important results. A basic statement is as follows: E (Y ) = E (E (Y X)). Here is a proof for the continuous case: E (E (Y X)) = = and for ...
