Limit theorems for the empirical distribution function of scaled increments of Itô semimartingales at high frequencies
Viktor Todorov, George Tauchen
We derive limit theorems for the empirical distribution function of "devolatilized" increments of an Itô semimartingale observed at high frequencies. These "devolatilized" incremen…

Nonparametric test for a constant beta between \Ito semi-martingales based on high-frequency data
Markus Reiß, Viktor Todorov, George Tauchen
We derive a nonparametric test for constant beta over a fixed time interval from high-frequency observations of a bivariate \Ito semimartingale. Beta is defined as the ratio of the…
