Symmetry and Time Changed Brownian Motions *

چکیده
In this paper we examine which Brownian Subordination with drift exhibits the symmetry property introduced by Fajardo and Mordecki (2006b). We obtain that when the subordination results in a Lévy process, a necessary and sufficient condition for the symmetry to hold is that drift must be equal to -1/2.

Exponents, symmetry groups and classification of operator fractional Brownian motions
Operator fractional Brownian motions (OFBMs) are zero mean, operator self-similar (o.s.s.), Gaussian processes with stationary increments. They generalize univariate fractional Brownian motions to the multivariate context. It is well-known that the so-called symmetry group of an o.s.s. process is conjugate to subgroups of the orthogonal group. Moreover, by a celebrated result of Hudson and Maso...
متن کاملOn Correlating Lévy Processes
A relatively simple approach to correlating unit period returns of Lévy processes is developed. We write the Lévy process as a time changed Brownian motion and correlate the Brownian motions. It is shown that sample correlations understate the required correlation between the Brownian motions and we show how to correct for this. Pairwise tests illustrate the adequacy of the model and the signi ...
متن کاملA Generalized Normal Mean Variance Mixture for Return Processes in Finance
Time-changed Brownian motions are extensively applied as mathematical models for asset returns in Finance. Time change is interpreted as a switch to trade-related business time, different from calendar time. Time-changed Brownian motions can be generated by infinite divisible normal mixtures. The standard multivariate normal mean variance mixtures assume a common mixing variable. This correspon...
متن کاملJ an 2 00 6 CGMY and Meixner Subordinators are Absolutely Continuous with respect to One Sided Stable
We describe the CGMY and Meixner processes as time changed Brownian motions. The CGMY uses a time change absolutely continuous with respect to the one-sided stable (Y/2) subordinator while the Meixner time change is absolutely continuous with respect to the one sided stable (1/2) subordinator. The required time changes may be generated by simulating the requisite one-sided stable subordinator a...
متن کاملWeighted-symmetry tests
Weighted-symmetry is an extension of the classical notion of symmetry in which the left and right probability tails are similar under a scaling transformation. The aim of this paper is to develop tests of weighted-symmetry based on some empirical processes. It is shown that the limiting distributions of these processes are Brownian bridges or Brownian motions. Moreover, it is proved that the Ho...
