On Partial Stochastic Comparisons Based on Tail Values at Risk
Mathematics, 2020 The tail value at risk at level p, with p ∈ ( 0 , 1 ) , is a risk measure that captures the tail risk of losses and asset return distributions beyond the p quantile. Given two distributions, it can be used to decide which is riskier.
