Differentially Private Ordinary Least Squares

open access: yesThe Journal of Privacy and Confidentiality, 2019
Linear regression is one of the most prevalent techniques in machine learning; however, it is also common to use linear regression for its explanatory capabilities rather than label prediction.

Non-parametric and least squares Langley plot methods [PDF]

open access: yesAtmospheric Measurement Techniques, 2016
Langley plots are used to calibrate sun radiometers primarily for the measurement of the aerosol component of the atmosphere that attenuates (scatters and absorbs) incoming direct solar radiation.

Estimating Detection Limits in Chromatography from Calibration Data: Ordinary Least Squares Regression vs. Weighted Least Squares

open access: yesSeparations, 2018
It is necessary to determine the limit of detection when validating any analytical method. For methods with a linear response, a simple and low labor-consuming procedure is to use the linear regression parameters obtained in the calibration to estimate ...

Total Least Squares Registration of 3D Surfaces [PDF]

open access: yesISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2013
Co-registration of point clouds of partially scanned objects is the first step of the 3D modeling workflow. The aim of coregistration is to merge the overlapping point clouds by estimating the spatial transformation parameters.

On the Least Median Square Problem [PDF]

open access: yesDiscrete & Computational Geometry, 2004
We consider the exact and approximate computational complexity of the multivariate least median-of-squares (LMS) linear regression estimator. The LMS estimator is among the most widely used robust linear statistical estimators. Given a set of n points in ${\Bbb R}^d$ and a parameter k, the problem is equivalent to computing the narrowest slab bounded ...

Teaching Least Squares in Matrix Notation

open access: yesRatio Mathematica, 2017
Material for teaching least squares at the undergraduate level in matrix notation is reported. The weighted least squares equations are first derived in matrix form; equivalence with the standard results obtained by standard algebra are then given for ...

The performance of unweighted least squares and regularized unweighted least squares in estimating factor loadings in structural equation modeling [PDF]

open access: yesInternational Journal of Data and Network Science, 2023
In a confirmatory study, researchers are expected to employ the covariance-based structural equation modeling (CB-SEM). One of the key presumptions when utilizing CB-SEM is that the data is multivariate normal.

Least Squares for Practitioners [PDF]

open access: yesMathematical Problems in Engineering, 2010
In experimental science and engineering, least squares are ubiquitous in analysis and digital data processing applications. Minimizing sums of squares of some quantities can be interpreted in very different ways and confusion can arise in practice, especially concerning the optimality and reliability of the results.

Least Trimmed Squares [PDF]

open access: yes, 2000
Least trimmed squares (LTS) is a statistical technique for estimation of unknown parameters of a linear regression model and provides a “robust” alternative to the classical regression method based on minimizing the sum of squared residuals.
