WebThe idea is to exploit the defining property (6) of conditional expectation. First, suppose that X ‚0. Define B to be the set of possible values of Y for which the conditional … Conditional expectation is unique up to a set of measure zero in . The measure used is the pushforward measure induced by Y . In the first example, the pushforward measure is a Dirac distribution at 1. In the second it is concentrated on the "diagonal" , so that any set not intersecting it has measure 0.

WebApr 23, 2024 · The conditional probability of an event A, given random variable X (as above), can be defined as a special case of the conditional expected value. As usual, let 1A denote the indicator random variable of A.
