Bipower variation什么意思
Webbipower variation estimates the quadratic variation of the jump component. This seems to be the first method which can divide up quadratic variation into its continuous and … WebThis paper provides limit distribution results for power variation, that is, sums of powers of absolute increments under nonequidistant subdivisions of time and for certain types of time-changed Brownian motion and α -stable processes. Special cases of these processes are stochastic volatility models used extensively in financial econometrics.

WebDec 1, 2014 · This paper inherits the intuition of the bipower variation estimation and extends the method to the correlated return process by modeling the price process using the fractal Brownian motion process. The fractal Brownian motion model has been used to model the long-memory in return series, thus the serial correlation in returns.
