Quasi-Optimal Cardinality of AFEM Driven by Nonresidual Estimators
Error reduction convergence optimal cardinality adaptive algorithm

2015/12/11
We examine adaptive finite element methods (AFEM) with any polynomial degree satisfying rather general assumptions on the a posteriori error estimators. We show that several non-residual estimat...
L-estimators and m-estimators for doubly censored data
Asymptotic normality asymptotic variance Fredholm integral equation Hadamard differentiability self-consistent estimator strong consistency

2015/12/11
Motivated by estimation and testing with doubly censored data, we study (robust) Lestimators and M-estimators based on such data. These estimators are given through functionals of the self-consistent ...

2015/12/11
We study the detailed structure (in a large sample) of the self-consistent estimators of the survival functions with doubly censored data. We also introduce the kernel-type density estimators based on...
On the finite sample properties of pre-test estimators of spatial models
Spatial models Spatial lag models

This paper explores the properties of pre-test strategies in estimating a linear Cliff–Ord-type spatial model when
the researcher is unsure about the nature of the spatial dependence. More speciʂ...
Nonlinear Estimators and Tail Bounds for Dimension Reduction in l1 Using Cauchy Random Projections

2015/8/21
For1 dimension reduction in the l1 norm, the method of Cauchy random projections multiplies the original data matrix A ∈ Rn×D with a random matrix R ∈ RD×k (k D) whose entries are i.i.d. samples of ...
ASYMPTOTIC MINIMAXITY OF WAVELET ESTIMATORS WITH SAMPLED DATA
Besov spaces bounded operators between Besov spaces

2015/8/20
Donoho and Johnstone (1998) studied a setting where data were obtained
in the continuum white noise model and showed that scalar nonlinearities applied
to wavelet coefficients gave estimators w...

2015/5/28
The entropy rate of a hidden Markov process (HMP) is important in theory and practical applications, but it is hard to get an analytical expression or obtain a numerical estimator. In this paper, a ne...
