WebDec 1, 2010 · Bipower variation is substantially biased if there is one jump in the trajectory (+48.04%) and greatly biased (+102.03%) if there are two jumps in the trajectory. If the two jumps are consecutive, the bias is huge (+595.57%) and can only be marginally softened by using staggered bipower variation (+97.07%, like for the case of two jumps). did ariana grande shave her headWebRealised bipower variation consistently estimates the quadratic variation of the contin-uous component of prices. In this paper we generalise this concept to realised bipower covariation, study its properties, illustrate its use, derive its asymptotic distribution and use it to test for jumps in multivariate price processes. did ariana grande say she hates america
