The conditional expectation (or conditional expected value, or conditional mean) is the expected value of a random variable, computed with respect to a ...

The conditional expectation E[ Y|A ] of Y w.r.t an event A is a deterministic number . The conditional expectation E[ Y|X ] of Y w.r.t a random variable X ...

Abstract. The goal of this document is to get the reader to some level of proficiency in calculating and manipulating conditional expectations and variances ...

Here, we will discuss the properties of conditional expectation in more detail as they are quite useful in practice. We will also discuss conditional variance.

Properties of Conditional Expectation: Let X ∈ L2(Ω,F,P) and let G be a σ ... Follow- ing is another property of conditional expectation that generalizes a ...

23 апр. 2022 г. · The conditional variance of Y given X is defined like the ordinary variance, but with all expected values conditioned on X. ... Thus, var(Y∣X) is ...

The corresponding characteristics will be random variables that can be represented as functions of X. The following properties can be mentioned: (a) E(Y + Z|X)) ...
