What is the expectation of this distribution? In math, the expectation of E[Y jX] is E[E[Y jX]], of course. The inner expectation is over Y, and the outer expectation is over X. To clarify, this could be written as E X [E Y [Y jX]], though this is rarely ...

WebIf I understand your question and assumptions, then the answer is yes. This does not require any independence, but it does require that your conditional expectations are zero for all values of the auxiliary variables..
