Robustness of Deepest Regression

open access: yesJournal of Multivariate Analysis, 2000
The notion of the regression depth is one of the most interesting and important notions recently studied in multivariate analysis. The authors investigate the robustness properties of deepest regressions. It is shown that the deepest regression functional is Fisher-consistent for the conditional median, and has a breakdown value of 1/3 in all ...

Robust reduced-rank regression [PDF]

open access: yesBiometrika, 2017
SummaryIn high-dimensional multivariate regression problems, enforcing low rank in the coefficient matrix offers effective dimension reduction, which greatly facilitates parameter estimation and model interpretation. However, commonly used reduced-rank methods are sensitive to data corruption, as the low-rank dependence structure between response ...

Robust Matrix Regression

open access: yesCoRR, 2016
Modern technologies are producing datasets with complex intrinsic structures, and they can be naturally represented as matrices instead of vectors. To preserve the latent data structures during processing, modern regression approaches incorporate the low-rank property to the model and achieve satisfactory performance for certain applications.

Estimating a unit price for roads maintenance activities using exponential robust regression

open access: yesJournal of Civil Engineering and Management, 2014
Good road maintenance schemes allow reducing costs and extending the service life of roads. There are several methods to plan these project maintenances but all of them require input information about maintenance costs, which can be very different ...

Robust analyzes for longitudinal clinical trials with missing and non-normal continuous outcomes

open access: yesStatistical Theory and Related Fields, 2023
Missing data is unavoidable in longitudinal clinical trials, and outcomes are not always normally distributed. In the presence of outliers or heavy-tailed distributions, the conventional multiple imputation with the mixed model with repeated measures ...

Understanding the determinants of happiness through Gallup World Poll

open access: yesJournal of Family Medicine and Primary Care, 2020
Background: The idea of happiness is as old as civilization, but breakthrough is achieved only in 20th century. Happiness can be broadly segmented into biological and behavioural component. The sufferings from illnesses hamper happiness.

MODIFIED FUZZY-ROBUST RIDGE REGRESSION FOR MULTICOLLINEAR, OUTLIER-CONTAMINATED DATA

open access: yesScience Journal of University of Zakho
Multicollinearity is known to have a significant impact on the stability of linear regression parameter estimation, while the presence of outliers tends to compound this problem. Ridge regression helps to improve the multicollinearity problem, but it is

An Efficient Estimation and Classification Methods for High Dimensional Data Using Robust Iteratively Reweighted SIMPLS Algorithm Based on nu-Support Vector Regression

open access: yesIEEE Access, 2021
The statistically inspired modification of the partial least squares (SIMPLS) is the most commonly used algorithm to solve a partial least squares regression problem when the number of explanatory variables ( $p$ ) is larger than the sample size ( $n$ ).
