Robust Surveillance Schemes Based on Proportional Hazard Model for Monitoring Reliability Data

open access: yesMathematics, 2023
Product reliability is a crucial component of the industrial production process. Several statistical process control techniques have been successfully employed in industrial manufacturing processes to observe changes in reliability-related quality ...

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 ...

The effect of calibration errors on the accuracy of the eye movement recordings

open access: yesJournal of Eye Movement Research, 2008
For calibrating eye movement recordings, a regression between spatially defined calibration points and corresponding measured raw data is performed.

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 ...

Robust nonparametric estimation via wavelet median regression [PDF]

open access: yes, 2008
In this paper we develop a nonparametric regression method that is simultaneously adaptive over a wide range of function classes for the regression function and robust over a large collection of error distributions, including those that are heavy-tailed,

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.

Model-robust regression and a Bayesian ``sandwich'' estimator [PDF]

open access: yes, 2010
We present a new Bayesian approach to model-robust linear regression that leads to uncertainty estimates with the same robustness properties as the Huber--White sandwich estimator.

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

Significance Regression: Robust Regression for Collinear Data [PDF]

open access: yes, 1993
This paper examines robust linear multivariable regression from collinear data. A brief review of M-estimators discusses the strengths of this approach for tolerating outliers and/or perturbations in the error distributions.
