  1. A nonparametric regression method for multiple longitudinal phenotypes using multivariate adaptive splines

    In genetic studies of complex diseases, particularly mental illnesses, and behavior disorders, two distinct characteristics have emerged in some data...

    Wensheng Zhu, He** Zhang in Frontiers of Mathematics in China
    Article 15 November 2012
  2. Non-parametric estimation of the diffusion coefficient from noisy data

    We consider a diffusion process ( X t ) t  ≥ 0 , with drift b ( x ) and diffusion coefficient σ ( x ). At discrete times t k  =  k δ for k from 1 to M , we...

    Article 27 September 2012
  3. Model selection and sharp asymptotic minimaxity

    We obtain sharp minimax results for estimation of an n -dimensional normal mean under quadratic loss. The estimators are chosen by penalized least...

    Zheyang Wu, Harrison H. Zhou in Probability Theory and Related Fields
    Article 17 March 2012
  4. Model averaging for semiparametric additive partial linear models

    To improve the prediction accuracy of semiparametric additive partial linear models (APLM) and the coverage probability of confidence intervals of...

    GuoHua Deng, Hua Liang in Science China Mathematics
    Article 26 April 2010
  5. How to Compare Different Loss Functions and Their Risks

    Many learning problems are described by a risk functional which in turn is defined by a loss function, and a straightforward and widely known...

    Ingo Steinwart in Constructive Approximation
    Article 04 April 2007
  6. Sequential Kernel Estimation of the Conditional Intensity of Nonstationary Point Processes

    This paper develops adaptive nonparametric methods for analyzing seismic data. Kernel smoothing techniques are suitable for space–time point...

    Article 01 July 2006
  7. On a Strategy to Develop Robust and Simple Tariffs from Motor Vehicle Insurance Data

    The goals of this paper are twofold: we describe common features in data sets from motor vehicle insurance companies and we investigate a general...

    Andreas Christmann in Acta Mathematicae Applicatae Sinica
    Article 01 May 2005
  8. On the efficiency of selection criteria in spline regression

    This paper concerns the cubic smoothing spline approach to nonparametric regression. After first deriving sharp asymptotic formulas for the...

    Article 04 July 2003
  9. A Comparison Between L1 Markov Random Field-based and Wavelet-based Estimators

    We consider the problem of denoising a one-dimensional signal modeled as the realization of a Markov random field (MRF) by maximizing its posterior...
    Sylvain Sardy, Cédric Bilat, ... Valérie Chavez-Demoulin in Statistical Data Analysis Based on the L1-Norm and Related Methods
    Conference paper 2002
  10. Prediction of 0–1-Events for Short- and Long-memory Time Series

    The problem of predicting 0–1-events is considered under general conditions, including stationary processes with short and long memory as well as...
