Asymptotic expansion of variations
Nakahiro Yoshida University of Tokyo, Institute of Statistical Mathematics, and JST CREST Abstract We consider limit theorems for variations of high frequency data under the finite time horizon. The error distributions are asymptotically mixed normal. The non-ergodic martingale expansion is applied to the p-variation and the realized volatility with microstructure noise.
