Conditional tail expectation definition
WebMay 15, 2014 · The MES has also been studied under the name ‘conditional tail expectation’ (CTE). The definition of the CTE in a univariate context is the same as that of the tail value at risk. Mathematically, it is given by E {X X > Q X (1 − p)} where Q X is the quantile function of X. When X has a continuous distribution, this is also called the ... WebDefinition of Conditional Expectation. For random variables defined on discrete proba-bility spaces, conditional expectation can be defined in an elementary manner: In particular, the conditional expectation of a discrete random variable X given the value y of another dis-crete random variable Y may be defined by (5) E(X jY ˘ y) ˘ X x xP ...
