Moments of standardized Fernandez–Steel skewed distributions: Applications to the estimation of GARCH-type models

2016-8, Trottier, Denis-Alexandre, Ardia, David

We provide general expressions for obtaining raw, absolute and conditional moments for a standardized version of the class of skewed distributions proposed by Fernandez and Steel (1998). We show that these expressions are readily programmable in addition of greatly reducing the computational cost. We discuss several applications that are relevant for the purpose of estimating asymmetric conditional volatility models under skewed distributions.

A Note on Jointly Backtesting Models for Multiple Assets and Horizons

2016-5, Ardia, David, Guerrouaz, Anas, Hoogerheide, Lennart

We propose a simulation-based methodology, which allows us to test the performance of multi-level and/or multi-horizon value-at-risk forecasts.
