WebThe reason for this is that while you are using an independent copy of X, the bound on X − Y would be the same if Y was an anti-correlated version of X, in other words if Y = − X. In this case X − Y = 2 X and the variance of 2 X is four times that of X, not twice. WebNov 9, 2024 · Conditional variance is defined as Var ( X G) := E [ ( X − E [ X G]) 2 G]. I have so far been able to show that Var ( X G) = E [ X 2 G] − E [ X G] 2 and E [ ( X − ζ) 2 G] = E ( X 2 G) − 2 ζ E [ X G] + ζ 2 using definitions of conditional expectation.

Also, the bound only involves the variance under Qnot P, which is consistent with the asymmetry of ˜2-divergence.
