The fractional Vasicek model with long-range dependence is assumed to be driven by a fractional Brownian motion with the Hurst parameter greater than or equal to one half. It is shown that, when the Hurst parameter is known, the asymptotic theory for the persistence parameter depends critically on its sign, corresponding asymptotically to the stationary case, the explosive case, and the null

The fractional Vasicek model with long-range dependence is assumed to be driven by a fractional Brownian motion with the Hurst parameter We study the parameter estimation problem of Vasicek Model driven by sub-fractional Brownian processes from discrete observations, and let S_t^H,t>=0 denote a sub-fractional Brownian motion whose Hurst parameter 1/2

This paper developed an inference problem for Vasicek model driven by a general Gaussian process. We construct a least squares estimator and a moment estimator for the drift parameters of the Vasicek model, and we prove the consistency and the asymptotic normality.

It is a type of one-factor short-rate model as it describes interest rate movements as driven by only one source of market risk. The model can be used in the valuation of interest rate derivatives, and has also been adapted for credit markets. It was introduced in 1977 by Oldřich Vašíček, and can be also seen as a stochastic investment model. 2020-09-20 · This paper developed an inference problem for Vasicek model driven by a general Gaussian process.

Vasicek model, for example, discontinuous sample paths and the Brownian motion by non-Gaussian noise. Recently, the parameter estimation problems for Vasicek model driven by small Levy noises have been studied by some authors. For´ example, Davis( [11]) used Malliavin calculus and Monte Carlo estimation to study the estimator of the Vasicek model

413-935-2682 parameter estimation for Vasicek model driven by Brownian motion has been well developed( [13], [18], [22]). However, some features of the ﬁnancial processes cannot be captured by the Vasicek model, for example, discontinuous sample paths and heavy tailed properties. Therefore, it is natural to replace the Brownian motion by the Levy process In this paper, an estimate of the drift and diffusion parameters of the extended Vasiček model is presented.

That is, the parameter estimation of the so-called Vasicek-type model driven by sub-fractional Brownian motion: dX t= (m+qXt)dt +dSH, t 0, (2) where SH is a sub-fractional Brownian motion and m 2R, q 2R+ are two unknown parameters. On the other hand, there exists still a practical motivation for studying the parameter estimation, that
