Tail expectation formula

Web9 Jun 2024 · Calculate the deviation between each value and the expected value: Square the values and multiply them by their probability: Sum the values and take the square root: σ = √ (0.242 + 0.005 + 0.243) σ = √ (0.49) σ = 0.7 eggs How to test hypotheses using null distributions Null distributions are an important tool in hypothesis testing. WebThis study investigates the problem by focusing on an important risk measure, the conditional tail expectation (CTE), under a general multivariate stochastic volatility model. To overcome the estimation difficulties caused by the long period, we derive an asymptotic formula to approximate the CTE.
