ANOVA FOR DIFFUSIONS AND ITO PROCESSES
- SUBMITTED TO THE ANNALS OF STATISTICS
"... Ito processes are the most common form of continuous semimartingales, and include diffusion processes. The paper is concerned with the nonparametric regression relationship between two such Ito processes. We are interested in the quadratic variation (integrated volatility) of the residual in this re ..."

continuous Itô process
, 2008
"... In this paper, we consider a d-dimensional continuous Itô process which is observed at n regularly spaced times on a given time interval [0,T]. This process is driven by a multidimensional Wiener process and our aim is to provide asymptotic statistical procedures which give the minimal dimension of ..."

Discrete sampling of functionals of Itô processes.
, 2004
"... For a multidimensional Itô process (Xt)t≥0 driven by a Brownian motion, we are interested in approximating the law of ψ () (Xs)s∈[0,T] , T> 0 deterministic, for a given functional ψ using a discrete sample of the process X. For various functionals (related to the maximum, to the integral of the p ..."

ON THE FIRST TIME THAT AN ITO PROCESS HITS
"... Abstract. This work deals with first hitting time densities of Ito processes whose local drift can be modeled in terms of a solution to Burgers equation. In particular, we derive the densities of the first time that these processes reach a moving boundary. We distinguish two cases: (a) the case in w ..."

1 Ito Processes with Finitely Many States of Memory
, 2007
"... We show that Ito processes imply the Fokker-Planck (K2) and Kolmogorov backward time (K1) partial differential eqns. (pde) for transition densities, which in turn imply the Chapman-Kolmogorov equation without approximations. This result is not restricted to Markov processes. We define ‘finite memory ..."

Matching Statistics of an Itô Process by a Process of Diffusion Type
, 2010
"... Suppose we are given a multi-dimensional Itô process, which can be regarded as a model for an underlying asset price together with related stochastic processes, e.g., volatility. The drift and diffusion terms for this Itô process are permitted to be arbitrary adapted processes. We construct a weak s ..."

Mimicking an Itô process by a SOLUTION OF A STOCHASTIC DIFFERENTIAL EQUATION
, 2012
"... Given a multi-dimensional Itô process whose drift and diffusion terms are adapted processes, we construct a weak solution to a stochastic differential equation that matches the distribution of the Itô process at each fixed time. Moreover, we show how to match the distributions at each fixed time of ..."
