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.

WebIf we get 4 heads then a tail, the expected number is e + 5. Finally, if our first 5 tosses are heads, then the expected number is 5. Thus e = 1 2 ( e + 1) + 1 4 ( e + 2) + 1 8 ( e + 3) + 1 16 ( e + 4) + 1 32 ( e + 5) + 1 32 ( 5). Solve this linear equation for e. We get e = 62.

WebThe most common choice among these coherent measures of risk is, undoubtedly, the Conditional Tail Expectation (CTE), also known as Conditional Value at Risk (CVaR), Tail Value at Risk (TVaR), Average Value at Risk(AVaR), Expected Tail Loss, etc. WebLower tail bound: P(X (1 ) ) exp 2 2 where exp(x) = ex. The Cherno bound will allow us to bound the probability that Xis larger than some multiple of its mean, or less than or equal to it.
