Power and Bipower Variation with Stochastic Volatility and Jumps

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. WebVolatility Decomposition. Asset prices are usually modeled as a continuous diffusion process with random jumps. By decomposing an asset's price variance into continuous and jump components, better risk management and asset allocation for a portfolio can be achieved. In order to compute price variations, returns are first calculated and ... highland animal clinic ak https://southernkentuckyproperties.com
