WebGiven the increasing popularity of the bipower volatility estimator, an important topic for future research is the development of formal rules for choosing the critical or optimal sampling frequency. In addition, it would appear to be useful to develop kernel-based or subsampling-based extensions to volatility estimators that are based on the ...

WebNov 2, 2010 · The characterization of return distributions and forecast of asset-price variability play a critical role in the study of financial markets. This study estimates four measures of integrated volatility—daily absolute returns, realized volatility, realized bipower volatility, and integrated volatility via Fourier transformation (IVFT)—for gold, …
Webcommonly used estimators of variation such as realized volatility, but it also encompasses more recently suggested quantities such as realized power varia-tion and realized bipower variation. We considerably strengthen existing results on the latter two quantities, deepening our understanding and unifying their treatment. WebHowever, as the Bipower variation and the realized volatility exhibit similar char-acteristics (see Section 2.2.2) we can adopt the approaches developed for realized volatility models to the Bipower variation. We therefore start the discussion of our multivariate model with the specification of the Bipower variation equation, proceed with the ...
WebWe build a discrete-time non-linear model for volatility forecasting purposes. This model belongs to the class of threshold-autoregressive models, where changes in regimes are governed by past returns. The ability to capture changes in volatility regimes and using more accurate volatility measures allow outperforming other benchmark models, such …
