Anti-robust and tonsured statistics [PDF]

open access: yesModel Assisted Statistics and Applications, 2017
This describes a statistical technique called “tonsuring” for exploratory data analysis in finance. Instead of rejecting “outlier” data that conflicts with the model, this strips out “inlier” data to get a clearer picture of how the market changes for larger moves.

Robust Wavelength Selection Using Filter-Wrapper Method and Input Scaling on Near Infrared Spectral Data

open access: yesSensors, 2020
The extraction of relevant wavelengths from a large dataset of Near Infrared Spectroscopy (NIRS) is a significant challenge in vibrational spectroscopy research.

A Robust Method for Gaussian Profile Estimation in the Case of Overlapping Objects

open access: yesIEEE Access, 2021
The precise stellar object identification is one of the major research fields in astronomy. In astronomical images, the 2D Gaussian function provides a good approximation of stellar objects.

Robust correlation analyses: false positive and power validation using a new open source Matlab toolbox

open access: yesFrontiers in Psychology, 2013
Pearson’s correlation measures the strength of the association between two variables. The technique is, however, restricted to linear associations and is overly sensitive to outliers.

Influence Analysis of Robust Wald-type Tests [PDF]

open access: yes, 2015
We consider a robust version of the classical Wald test statistics for testing simple and composite null hypotheses for general parametric models. These test statistics are based on the minimum density power divergence estimators instead of the maximum ...

Statistical Procedures and Robust Statistics [PDF]

open access: yes, 2002
It is argued that a main aim of statistics is to produce statistical procedures which in this article are defined as algorithms with inputs and outputs. The structure and properties of such procedures are investigated with special reference to topological and testing considerations.

Transcriptomic pan‐cancer analysis using rank‐based Bayesian inference

open access: yesMolecular Oncology, 2023
The analysis of whole genomes of pan‐cancer data sets provides a challenge for researchers, and we contribute to the literature concerning the identification of robust subgroups with clear biological interpretation.

Cross-validation in nonparametric regression with outliers [PDF]

open access: yes, 2005
A popular data-driven method for choosing the bandwidth in standard kernel regression is cross-validation. Even when there are outliers in the data, robust kernel regression can be used to estimate the unknown regression curve [Robust and Nonlinear Time ...

The Use of Modern Robust Regression Analysis with Graphics: An Example from Marketing

open access: yesStats
Routine least squares regression analyses may sometimes miss important aspects of data. To exemplify this point we analyse a set of 1171 observations from a questionnaire intended to illuminate the relationship between customer loyalty and perceptions of

On the efficiency of Gini's mean difference [PDF]

open access: yes, 2014
18 pages, 3 figures, 8 tables Acknowledgments We are indebted to Herold Dehling for introducing us to the theory of U-statistics, to Roland Fried for introducing us to robust statistics, and to Alexander Dürre, who has demonstrated the benefit of complex
