A new paradigm of adaptivity is to execute re nement, coarsening, and smoothing
of meshes on manifolds with incomplete information about their geometry and yet preserve position
and curvature accura...
On self-consistent estimators and kernel density estimators with doubly censored data
Asymptotic normality Failure rate function Right censored data: Survival distribution Uniform strong consistency
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...

2015/8/21
Fisher-consistent loss functions play a fundamental role in the construction of successful binary margin-based classifiers. In this paper we establish the Fisher-consistency condition for multicategor...
This paper studies the formation of risk-sharing networks through costly social
investments, identifying endogenous inequality and a misallocation of resources as possible
downsides to such agreemen...

A new type of the KP equation with self-consistent sources (KPESCS)
痳st found by Melnikov ( Lett. Math. Phys. 7(1983) 129-136)is re-constructed
via source generation procedure. New feature of the ob...

Consistent testing for a constant copula under strong mixing based on the tapered block multiplier technique
Change point test Copula Empirical copula process Nonparametric estimation Time series Strong mixing Multiplier central limit theorem
2012/6/29
Considering multivariate strongly mixing time series, nonparametric tests for a constant copula with specified or unspecified change point (candidate) are derived; the tests are consistent against gen...
Non-consistent approximations of self-adjoint eigenproblems: Application to the supercell method
Non-consistent approximations self-adjoint eigenproblems Functional Analysis
2012/5/24
In this article, we introduce a general theoretical framework to analyze non-consistent approximations of the discrete eigenmodes of a self-adjoint operator. We focus in particular on the discrete eig...
Nonparametrically consistent depth-based classifiers
Affine-invariance Classification procedures Nearest Neighbors Statistical depth functions Symmetrization
2012/4/16
We introduce a class of depth-based classification procedures that are of a nearest-neighbor nature. Depth, after symmetrization, indeed provides the center-outward ordering that is necessary and suff...

2011/9/5
Abstract: We study a family of Markov processes on $\mathcal{P}^{(k)}$, the space of partitions of the natural numbers with at most $k$ blocks. The process can be constructed from a Poisson point proc...
On non-multiaffine consistent around the cube lattice equations
Integrable lattice equations Yang-Baxter maps Consistency around the cube
2011/7/5
We show that integrable involutive maps, due to the fact they admit three integrals in separated
form, can give rise to equations which are consistent around the cube and which are not in the multiaf...
Self-Consistent Stochastic Model Errors in Data Assimilation

2010/12/28
In using data assimilation to import information from observations to estimate parameters
and state variables of a model, one must assume a distribution for the noise in the measure-
ments and in th...
