Empirical risk minimization for heavy-tailed losses

open access: yes, 2015
The purpose of this paper is to discuss empirical risk minimization when the losses are not necessarily bounded and may have a distribution with heavy tails.

Robust rank correlation based screening [PDF]

open access: yes, 2012
Independence screening is a variable selection method that uses a ranking criterion to select significant variables, particularly for statistical models with nonpolynomial dimensionality or "large p, small n" paradigms when p can be as large as an ...

Sensitivity and robustness in MDS configurations for mixed-type data: a study of the economic crisis impact on socially vulnerable Spanish people [PDF]

open access: yes
Multidimensional scaling (MDS) techniques are initially proposed to produce pictorial representations of distance, dissimilarity or proximity data. Sensitivity and robustness assessment of multivariate methods is essential if inferences are to be drawn ...

Confidence intervals for average success probabilities [PDF]

open access: yes, 2014
We provide Buehler-optimal one-sided and some valid two-sided confidence intervals for the average success probability of a possibly inhomogeneous fixed length Bernoulli chain, based on the number of observed successes.

Fence methods for mixed model selection

open access: yes, 2008
Many model search strategies involve trading off model fit with model complexity in a penalized goodness of fit measure. Asymptotic properties for these types of procedures in settings like linear regression and ARMA time series have been studied, but ...

Regenerative block empirical likelihood for Markov chains

open access: yes, 2011
Empirical likelihood is a powerful semi-parametric method increasingly investigated in the literature. However, most authors essentially focus on an i.i.d. setting.

Robust nonparametric inference for the median

open access: yes, 2005
We consider the problem of constructing robust nonparametric confidence intervals and tests of hypothesis for the median when the data distribution is unknown and the data may contain a small fraction of contamination.

Trimmed Likelihood Estimation of the Parameters of the Generalized Extreme Value Distributions: a Monte-Carlo Study [PDF]

open access: yes, 2005
2000 Mathematics Subject Classification: Primary 62F35; Secondary 62P99The applicability of the Trimmed Likelihood Estimator (TLE) proposed by Neykov and Neytchev to the extreme value distributions is considered.
