Law Of Iterated Expectations. 52 Discrete Conditional Expectation Part 2 Linearity, Law of Total Expectation YouTube At the end of the document it is explained why (note, both mean exactly the same!) The Law of Iterated Expectations (LIE) states that: \[\begin{equation} \mathbb{E}[X] = \mathbb{E}[\mathbb{E}[X|Y]] \end{equation}\] In plain English, the expected value of \(X\) is equal to the expectation over the conditional expectation of \(X\) given \(Y\)

What is the expectation of this distribution? In math, the expectation of E[Y jX] is E[E[Y jX]], of course The proposition in probability theory known as the law of total expectation, [1] the law of iterated expectations [2] (LIE), Adam's law, [3] the tower rule, [4] and the smoothing theorem, [5] among other names, states that if is a random variable whose expected value ⁡ is defined, and is any random variable on the same probability space, then ⁡ = ⁡ (⁡ ()),

The proposition in probability theory known as the law of total expectation, [1] the law of iterated expectations [2] (LIE), Adam's law, [3] the tower rule, [4] and the smoothing theorem, [5] among other names, states that if is a random variable whose expected value ⁡ is defined, and is any random variable on the same probability space, then ⁡ = ⁡ (⁡ ()), More simply, the mean of X is equal to a weighted. Sometimes you may see it written as E(X) = E y(E x(XjY))

Law of Iterated Expectations StuDocu. 3.1 Law of Iterated Expectations Since E[Y jX]is a random variable, it has a distribution More simply, the mean of X is equal to a weighted.
