Modeling and evaluating conditional quantile dynamics in VaR forecasts

open access: yes, 2023
We focus on the time-varying modeling of VaR at a given coverage $\tau$, assessing whether the quantiles of the distribution of the returns standardized by their conditional means and standard deviations exhibit predictable dynamics. Models are evaluated
