LINEAR REGRESSION WITH R AND HADOOP [PDF]

open access: yesChallenges of the Knowledge Society, 2015
In this paper we present a way to solve the linear regression model with R and Hadoop using the Rhadoop library. We show how the linear regression model can be solved even for very large models that require special technologies.

Ellipsoid Method for Linear Regression Parameters Determination

open access: yesКібернетика та комп'ютерні технології, 2020
Introduction. Linear regression parameters determination can be formulated as a non-smooth function minimization problem, which is Lp-norm of residual of the linear equations system.

Piecewise Linear Regression Based on Plane Clustering

open access: yesIEEE Access, 2019
Piecewise linear regressions have shown many successful applications in image denoising, signal process, and data mining fields. In essence, they attempt to seek multiple linear functions (piecewise/stepwise function) to fit the given scatter data points

Imputing missing values using cumulative linear regression

open access: yesCAAI Transactions on Intelligence Technology, 2019
The concept of missing data is important to apply statistical methods on the dataset. Statisticians and researchers may end up to an inaccurate illation about the data if the missing data are not handled properly.
