WebThe conditional expectation of a random variable Y is the expected value of Y given [X=x], and is denoted: E[Y X=x] or E[Y x]. If the conditional probability density function is … In probability theory, the conditional expectation, conditional expected value, or conditional mean of a random variable is its expected value – the value it would take “on average” over an arbitrarily large number of occurrences – given that a certain set of "conditions" is known to occur. If the random variable can take on only a finite number of values, the “conditions” are that the variable can only take on a subset of those values. More formally, in the case when the random variable …
