Maximum likelihood Estimation for Stochastic Differential Equations with two Random Effects in the Diffusion Coefficient
Journal Title: JOURNAL OF ADVANCES IN MATHEMATICS - Year 2016, Vol 11, Issue 10
Abstract
We study n independent stochastic processes(xi (t),tiЄ[o,t1 ],i=1,......n) defined by a stochastic differential equation with diffusion coefficients depending nonlinearly on a random variables and (the random effects).The distributions of the random effects фi,and,μi and depends on unknown parameters which are to be estimated from the continuous observations of the processes xi (t) . When the distributions of the random effects ф ,μ, are Gaussian and exponential respectively, we obtained an explicit formula for the likelihood function and the asymptotic properties (consistency and asymptotic normality) of the maximum likelihood estimator (MLE) are derived when tend to infinity.

Existence and uniqueness of mild solutions of nonlinear difference-integrodifferential equation with nonlocal condition
In this paper we investigate the existence, uniqueness and continuous dependence of solutions of the difference-integrodifferential equations. The results are obtained by using the well known Banach fixed point theorem,...
A Simulation Comparison of Bootstrap Procedures in Periodically Correlated Time Series Models
The presence of periodicity in data with periodic structure has become an important issue in parameter estimation. Several methods have been studied with intention estimating different parameters or constructing confiden...
Comparative Study of Various Measures of Dispersion
Statistical is a subject of mathematics, computers, management, business etc. Central tendency and measures of dispersion are two major aspects of statistical methods. Measures of dispersion are the statistical form...
