Conditional tail expectation definition
Tail value at risk (TVaR), also known as tail conditional expectation (TCE) or conditional tail expectation (CTE), is a risk measure associated with the more general value at risk. It quantifies the expected value of the loss given that an event outside a given probability level has occurred. See more There are a number of related, but subtly different, formulations for TVaR in the literature. A common case in literature is to define TVaR and average value at risk as the same measure. Under some formulations, it is … See more Closed-form formulas exist for calculating TVaR when the payoff of a portfolio $${\displaystyle X}$$ or a corresponding loss See more WebLecture 10: Conditional Expectation 10-2 Exercise 10.2 Show that the discrete formula satis es condition 2 of De nition 10.1.

Acerbi and Tasche, 2002; Artzner, 1999; Tasche, 2002; Wirch and Hardy, 1999 ). The CTE risk measure is the conditional expectation of the loss random …
WebFurthermore, by relegating the tail expectation formula to an end-of-chapter exercise, regrettably few texts discuss the probabilistic interpretation and practical usage of this unconventional expectation formula, which is radically di erent from the traditional way to calculate expectations by probability density or mass functions.

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 ...
