Bipower volatility
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, … WebSummary. In the framework of stochastic volatility models there is a wide range of applications of power, bipower and multipower variation, i.e. the sum of appropriately scaled absolute values of log-returns and neighbouring log-returns raised to a certain power. Given high frequency data we can use the concept of power and multipower variation ...

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 …
WebMay 23, 2006 · In this paper we provide an asymptotic analysis of generalized bipower measures of the variation of price processes in financial economics. These measures encompass the usual quadratic variation, power variation, and bipower variations that have been highlighted in recent years in financial econometrics.

WebJan 1, 2008 · Essentially, threshold bipower variance replaces the simple logreturn with the corrected return, r C 1 (r t+j∆ , θ t+j∆ ) that takes the expected return r e (θ t+j∆ ) 5 when … 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.
