Persistence as a Challenge to Volatility Modeling

BackgroundI Direct measurement of volatility: ideal properties of the

estimators ex postI Modeling for forecasting purposes: dynamic modelsI Clustering features are presentI Choice of modeling volatility or logvolatilityI Residual diagnostics as a guideline to specificationI Possible recalcitrant residual correlation as a guide to
