Regression model

This paper presents optimization results of the Al6061 surface roughness in turning ultra-precision based on the central composite design method (CCD) and the grey wolf optimization algorithm (GWO). The experimental matrix is built with three independent variables including spindle speed, feed rate and depth of cut. With the experimental data, the roughness regression model is established.

In this study, one analytical procedure was established for simultaneous determination based on UV-Vis spectrometry coupled with several multivariate linear regress solved by Python – an open language programme to quantify three antibiotics, including TET, PGP, and CEX, in laboratoryprepared synthetic and pharmaceutical mixtures. This study also provided a universally analytical procedure for determining the three antibiotics in their pharmaceutical forms without the need for optimization for each analyte.

This paper proposes regression models to investigate the impact of ESG scores and other factors on foreign ownership in Vietnamese listed firms. ESG scores, as a valuable tool for measuring a firm's environmental, social, and governance performance, provide foreign investors with insights into investment risks and potential, enabling them to determine optimal ownership levels for maximising returns.

This study examines the impact of alternative energy resources, natural resources, and government spending on France's ecological sustainability from 2000 to 2021, emphasizing the Environmental Kuznets Curve (EKC) framework and the theory of linear regression models. The findings reveal an inverse relationship between CO2 emissions and renewable energy and nuclear share on both total energy supply and final consumption.

This thesis investigates the choice behaviour of first year undergraduate students through proposing and testing a conceptual model. The psychological constructs of personal values, motivation, selection criteria, demographic and socioeconomic factors introduced as underlying drivers provide invaluable insight into the pathways of influence and relationships between student types and their preference towards a particular degree program at a particular university.

Two major areas of the scorecard development process were identified as having much capacity for improving credit scoring models. These are the application of 1) better classifiers and 2) variable selection techniques. However, the application of an artificial immune system for developing scorecards as well as the use of other variable selection techniques, other than stepwise regression, in credit scoring are quite limited as indicated by the scarcity of published materials in these two areas in the current literature.
