Using Exponentially Weighted Quantile Regression to Estimate Value at Risk and Expected Shortfall
We propose exponentially weighted quantile regression (EWQR) for estimating time-varying quantiles. The EWQR cost function can be used as the basis for estimating the time-varying expected shortfall associated with the EWQR quantile forecast. We express EWQR in a kernel estimation framework, and the...
