Limit theorems for bipower variation in financial econometrics [PDF]
arXiv, 2005 In this paper we provide an asymptotic analysis of generalised bipower measures of the variation of price processes in financial economics. These measures encompass the usual quadratic variation, power variation and bipower variations which have been highlighted in recent years in financial econometrics.
