چکیده

We present conditions to obtain the asymptotic normality of the maximum likelihood estimator of a loss process presented in [2]. We shall use the notations of [2], write ‖ · ‖q for the standard L norm on an arbitrary space R, d ≥ 1, and let D φ denote the k−th order di erentiation with respect to φ. Let us introduce the following hypotheses: (A4) For all i ∈ {1, . . . , r}, λi(Φ0) > 0. (A5) For all e, if PΦ0(E = e) > 0, then for all j ∈ {1, . . . , r}, pj(e, Φ0) > 0. (A6) For all j ∈ {1, . . . , r}, all e 6= ∅ and all x, the map φ 7→ Pθ(j, e, φ)(m ∈ e⇒ Xm = xm) is twice continuously di erentiable in FΦ0 . (A7) For all i, j ∈ {1, . . . , r} and all e 6= ∅, there exists a neighborhood G of Φ0 in FΦ0 such that 1. ∫ sup φ∈G ∥∥Dφ lnPθ(i, e, φ)(m ∈ e⇒ Xm = xm)∥∥22 Pθ(j, e,Φ0)(m ∈ e⇒ Xm = xm) dx <∞. 2. ∫ sup φ∈G ∥∥D2 φ lnPθ(i, e, φ)(m ∈ e⇒ Xm = xm)∥∥1 Pθ(j, e,Φ0)(m ∈ e⇒ Xm = xm) dx <∞.

Asymptotic Efficiencies of the MLE Based on Bivariate Record Values from Bivariate Normal Distribution

Abstract. Maximum likelihood (ML) estimation based on bivariate record data is considered as the general inference problem. Assume that the process of observing k records is repeated m times, independently. The asymptotic properties including consistency and asymptotic normality of the Maximum Likelihood (ML) estimates of parameters of the underlying distribution is then established, when m is ...

Consistency and Asymptotic Normality

The consistency and asymptotic normality of minimum contrast estimation (which includes the maximum likelihood estimation as a special case) is established if the sample is from a renewal process and the observation time tends to innnity. It is shown, that the conditions for consistency and asymptotic normality for maximum likelihood estimation are fulllled if the distribution of the time betwe...

Asymptotic Properties of Maximum Likelihood Es- Timation: Parameterised Diffusion in a Manifold

This paper studies maximum likelihood estimation for a parameterised elliptic diffusion in a manifold. The focus is on asymptotic properties of maximum likelihood estimates obtained from continuous time observation. These are well known when the underlying manifold is a Euclidean space. However, no systematic study exists in the case of a general manifold. The starting point is to write down th...

On the Asymptotic Normality of the Conditional Maximum Likelihood Estimators for the Truncated Regression Model and the Tobit Model

In this paper, we study the asymptotic normality of the conditional maximum likelihood (ML) estimators for the truncated regression model and the Tobit model. We show that under the general setting assumed in his book, the conjectures made by Hayashi (2000) 1 about the asymptotic normality of the conditional ML estimators for both models are true, namely, a sufficient condition is the nonsingul...

Robustness of the Separating Information Maximum Likelihood Estimation of the Realized Volatility with Micro-Market Noise

For estimating the realized volatility and covariance by using high frequency data, Kunitomo and Sato (2008a,b) have proposed the Separating Information Maximum Likelihood (SIML) method when there are micro-market noises. The SIML estimator has reasonable asymptotic properties; it is consistent and it has the asymptotic normality (or the stable convergence in the general case) when the sample s...

A Characterization of the Asymptotic Behaviour of Maximum Likelihood Estimators in Stochastic Evolution Systems

A spectral method is used to compute maximum likelihood estimators for parameters occuring in innnite dimensional stochastic evolution systems du(t) = (A 0 (t) + A 1 (t))u(t)dt + BdW(t) : The MLE's are based on nite dimensional approximations to solutions of such systems. We characterize the asymptotic behaviour of the estimators such as consistency and asymptotic normality as the dimension of ...
