Jun 10, 2022 · $$ = \mathbf{E}[h(X - \alpha \sigma^2)] = \mathbf{E}[h(X - \mathbf{Cov}(X,Y))]. $$ (Note that $\alpha\sigma^2 = \mathbf{Cov}(X, Y)$ .) This result can also be verified by a direct computation.
Feb 9, 2020 · Let X and Y be discrete random variables. Prove the linearity of expectation E(X+Y) = E(X) + E(Y). An exercise problem in probability theory. The solution is given.
The notion of di erential entropy is simply the divergence with respect to the Lebesgue measure: De nition 1.5. The di erential entropy of a random vector Xk is. h(Xk ) = h (PXk ) ≜ −D(PXkYLeb): (1.19) In particular, if X k 1 has probability density function (pdf) p, then h(Xk) = E log p(Xk); other-wise h(Xk) = −∞.
Covariance formula E [XY ] − E [X ]E [Y ], or “expectation of product minus product of expectations” is frequently useful. Note: if X and Y are independent then Cov(X , Y ) = 0.
