Diffusions with measurement errors. I. Local Asymptotic Normality [PDF]

open access: yesESAIM: Probability and Statistics, 2001
Summary: We consider a diffusion process \(X\) which is observed at times \(i/n\) for \(i=0,1,\dots,n\), each observation being subject to a measurement error. All errors are independent and centered Gaussian with known variance \(\rho_n\). There is an unknown parameter within the diffusion coefficient, to be estimated.

Asymptotics for L 1 $L_{1}$ -wavelet method for nonparametric regression

open access: yesJournal of Inequalities and Applications, 2020
Wavelets are particularly useful because of their natural adaptive ability to characterize data with intrinsically local properties. When the data contain outliers or come from a population with a heavy-tailed distribution, L 1 $L_{1}$ -estimation should

Local linear modelling of the conditional distribution function for functional ergodic data

open access: yesMathematical Modelling and Analysis, 2022
The focus of functional data analysis has been mostly on independent functional observations. It is therefore hoped that the present contribution will provide an informative account of a useful approach that merges the ideas of the ergodic theory and ...

Pseudo-Gaussian and Rank-Based Tests for First-Order Superdiagonal Bilinear Models in Panel Data

open access: yesRevstat Statistical Journal, 2021
In this paper, locally asymptotically optimal (in the H´ajek-Le Cam sense) parametric, pseudo-Gaussian and rank-based procedures are proposed for the problem of testing randomness against first-order superdiagonal bilinear panel dependence (in large n ...

Efficient Estimation in Heteroscedastic Varying Coefficient Models

open access: yesEconometrics, 2015
This paper considers statistical inference for the heteroscedastic varying coefficient model. We propose an efficient estimator for coefficient functions that is more efficient than the conventional local-linear estimator.

Integral Least-Squares Inferences for Semiparametric Models with Functional Data

open access: yesJournal of Applied Mathematics, 2014
The inferences for semiparametric models with functional data are investigated. We propose an integral least-squares technique for estimating the parametric components, and the asymptotic normality of the resulting integral least-squares estimator is ...

Statistical Inference for the Heteroscedastic Partially Linear Varying-Coefficient Errors-in-Variables Model with Missing Censoring Indicators

open access: yesDiscrete Dynamics in Nature and Society, 2021
In this paper, we focus on heteroscedastic partially linear varying-coefficient errors-in-variables models under right-censored data with censoring indicators missing at random.

The Local Linear M-Estimation with Missing Response Data

open access: yesJournal of Applied Mathematics, 2014
This paper studies the nonparametric regressive function with missing response data. Three local linear M-estimators with the robustness of local linear regression smoothers are presented such that they have the same asymptotic normality and consistency.
