Conditional tail expectation example
WebThe tail conditional expectation (henceforth, in short, TCE) is defined as. (1) This can be interpreted as the mean of very bad losses. It provides an average amount of the tail of the distribution which is usually based on the p -th quantile of the loss distribution with the property The associated TCE is given by.

WebDetails. The Conditional Tail Expectation is defined as CTE_{1-p} = E(X X>Q(1-p)) = E(X X>VaR_{1-p}) = VaR_{1-p} + \Pi(VaR_{1-p})/p, where \Pi(u)=E((X-u)_+) is the premium of the excess-loss insurance with retention u.. If the CDF is continuous in p, we have CTE_{1-p}=TVaR_{1-p}= 1/p \int_0^p VaR_{1-s} ds with TVaR the Tail Value-at-Risk..

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
