WebNov 19, 2016 · So, in generic terms, we are looking at the conditional expectation function E ( X ∣ Z) and not at the conditional expected value of X given a specific value Z = z. Then, E ( X ∣ Z) = g ( Z), i.e. it is a function of Z only, not of X, so it appears that its derivative with respect to X should be zero. WebWe try another conditional expectation in the same example: E[X2jY]. Again, given Y = y, X has a binomial distribution with n = y 1 trials and p = 1=5. The variance of such a …
WebNov 19, 2016 · By treating it as a decision/command variable, we effectively neutralize any aspect related to a random variable, the conditional expectation aspect in our case. … WebAs a second example, a recursive expression between higher order conditional expectations is found, which is shown to lead to a generalization of the Tweedy's identity. Finally, as a third example, it is shown that the k-th order derivative of the conditional expectation is proportional to the (k+1)-th order conditional cumulant.
