CVaR Regression Based on the Relation between CVaR and Mixed-Quantile Quadrangles [PDF]

open access: yesJournal of Risk and Financial Management, 2019
A popular risk measure, conditional value-at-risk (CVaR), is called expected shortfall (ES) in financial applications. The research presented involved developing algorithms for the implementation of linear regression for estimating CVaR as a function of some factors. Such regression is called CVaR (superquantile) regression.

A Reverse ES (CVaR) Optimization Formula

open access: yesNorth American Actuarial Journal, 2023
The celebrated Expected Shortfall (ES) optimization formula implies that ES at a fixed probability level is the minimum of a linear real function plus a scaled mean excess function. We establish a reverse ES optimization formula, which says that a mean excess function at any fixed threshold is the maximum of an ES curve minus a linear function. Despite
