Asymptotic Equivalence and Adaptive Estimation for Robust Nonparametric Regression

Asymptotic equivalence theory developed in the literature so far are only for bounded loss functions. This limits the potential applications of the theory because many commonly used loss functions in statistical inference are unbounded. In this paper we develop asymptotic equivalence results for robust nonparametric regression with unbounded loss functions. The results imply that all the Gaussi...

Asymptotic results for a barrier potential model

An enhanced understanding of the microstructure of oxide ceramics will help scientists and engineers improve their efficiency and design. A phase-field model for the composition and phase distribution of the oxide ceramic components is studied. The model, which includes an obstacle in the phase portion of the energy potential, results in a minimisation problem that characterises the distributio...

Model-Robust Designs for Quantile Regression

We give methods for the construction of designs for regression models, when the purpose of the investigation is the estimation of the conditional quantile function, and the estimation method is quantile regression. The designs are robust against misspecified response functions, and against unanticipated heteroscedasticity. The methods are illustrated by example, and in a case study in which the...

Asymptotic criteria for designs in nonlinear regression with model errors

We derive bounds for the design optimality criteria under the assumption that the supposed regression model y (xk) = η (xk, θ)+εk ; k = 1, 2, ... does not correspond to the true one. The investigation is based on the asymptotic properties of the LSE of θ, and full proofs of these properties are presented under the assumption that the sequence of design points {xk}k=1 is randomly sampled accordi...

Asymptotic Equivalence for Nonparametric Regression

We consider a nonparametric model E, generated by independent observations Xi, i = 1, ..., n, with densities p(x, θi), i = 1, ..., n, the parameters of which θi = f(i/n) ∈ Θ are driven by the values of an unknown function f : [0, 1]→ Θ in a smoothness class. The main result of the paper is that, under regularity assumptions, this model can be approximated, in the sense of the Le Cam deficiency ...
