These measures encompass the usual quadratic variation, power variation, and bipower variations that have been highlighted in recent years in financial econometrics. The analysis is carried out under some ... WebThe bipower variation process of order (r;s) for Y, denoted by V(Y;r;s)t, is the limit in probability, if it exists for all t 0, of V(Y;r;s)n t.

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 ... Web1We consider estimators using bipower increments with threshold, which will be referred to as threshold-bipower estimators, in Sections 3 and 4. However, for the simulation and empirical studies in Section 5, we also use the estimator using bipower increments without threshold truncation, that is, bipower estimators. Within our framework,
