Linear expectile regression under massive data

open access: yesFundamental Research, 2021
In this paper, we study the large-scale inference for a linear expectile regression model. To mitigate the computational challenges in the classical asymmetric least squares (ALS) estimation under massive data, we propose a communication-efficient divide

Shrinkage Estimators for the Intercept in Linear and Uplift Regression

open access: yesScientific Annals of Computer Science, 2023
Shrinkage estimators modify classical statistical estimators by scaling them towards zero in order to decrease their prediction error. We propose shrinkage estimators for linear regression models which explicitly take into account the presence ...

Linear regression in genetic association studies. [PDF]

open access: yesPLoS ONE, 2013
In genomic research phenotype transformations are commonly used as a straightforward way to reach normality of the model outcome. Many researchers still believe it to be necessary for proper inference. Using regression simulations, we show that phenotype

Robust Model Selection in Linear regression [PDF]

open access: yesKirkuk Journal of Science, 2007
The research deals with the proposing of robust formula for the accumulate prediction error (APE) criterion which is used in selecting regression model. The proposed formula evaluated with a simulation study.

MODELING CLUSTERWISE LINEAR REGRESSION ON POVERTY RATE IN INDONESIA

open access: yesBarekeng, 2023
When a person's income is so low that it cannot cover even the most basic living expenses, they are said to be poor. Data on poverty levels and hypothesized causes are used in this study. If the data pattern forms clusters, one of the regression analyses

Linear Regression for Heavy Tails

open access: yesRisks, 2018
There exist several estimators of the regression line in the simple linear regression: Least Squares, Least Absolute Deviation, Right Median, Theil–Sen, Weighted Balance, and Least Trimmed Squares.

Machine learning for credit scoring: Improving logistic regression with non-linear decision-tree effects

open access: yesEuropean Journal of Operational Research, 2021
In the context of credit scoring, ensemble methods based on decision trees, such as the random forest method, provide better classification performance than standard logistic regression models.

Bayesian linear regression for surface roughness prediction

open access: yes, 2020
To improve the prediction accuracy of surface roughness in milling process, this paper provides an unique feature extraction method and comprehensively analyzes four types of Bayesian linear regression (BLR) model (Standard_BLR, Gaussian_BLR ...

Conditional Linear Regression

open access: yesProceedings of the AAAI Conference on Artificial Intelligence, 2018
Previous work in machine learning and statistics commonly focuses on building models that capture the vast majority of data, possibly ignoring a segment of the population as outliers. By contrast, we may be interested in finding a segment of the population for which we can find a linear rule capable of achieving more accurate ...
