Response of the ordinary least squares estimator (OLS) to deterministic and stochastic noise

Proceedings of IEEE. AFRICON '96, 2002
Mapping functions and OPDFs (optimum parameter driving functions) defined in this paper are simple, intuitive, and useful tools for evaluating OLS parameter estimates. Parameter errors equal the inner product of the noise waveform and the mapping functions.

An examination of residual distributions in Ordinary Least Squares (OLS) household- based trip generation models

Transportation Research, 1976
Abstract It is shown that the residual distributions obtained from typical OLS household-based trip generation models do not comply with the assumptions inherent in the use of ordinary least-squares. In particular, heteroscedasticity is likely to occur invalidating the estimation of coefficient standard errors by OLS procedure.

Applying an Ordinary Least Squares (OLS) Regression Model On Processed Air Quality and Environment Data

British Journal of Environmental Sciences
This scientific research is primarily based on real-time data collected on air quality. A comprehensive and extensive study was initially conducted to explore the key factors contributing to air pollution. Other relevant information will encompass additional components such as PM10, PM1, and weather-related factors like temperature, humidity, and air ...

Evaluation of Ordinary Least Square (OLS) and Geographically Weighted Regression (GWR) for Water Quality Monitoring: A Case Study for the Estimation of Salinity

Journal of Ocean University of China, 2018
Landsat-5 Thematic Mapper (TM) dataset have been used to estimate salinity in the coastal area of Hong Kong. Four adjacent Landsat TM images were used in this study, which was atmospherically corrected using the Second Simulation of the Satellite Signal in the Solar Spectrum (6S) radiative transfer code.

THE IMPACT OF INFLATION ON GDP GROWTH: AN ANALYSIS USING ORDINARY LEAST SQUARES (OLS)

The Social Science Review A Multidisciplinary Journal
In this paper, correlations between the time trajectories of inflation rate and GDP growth rate in Cambodia are investigated by employing an ordinary least squares (OLS) regression model, which is a simplicity and suitable to estimate linear association between variables.

Analisis Penyebaran Demam Berdarah Dengue (DBD) Menggunakan Model SEIR-SI Serta Estimasi Parmater Dengan Metode Ordinary Least Squares (OLS)

Demam Berdarah Dengue (DBD) merupakan penyakit menular yang masih menjadi ancaman serius di Indonesia. Dalam penelitian ini, model SEIR-SI digunakan untuk memodelkan penyebaran DBD dengan mempertimbangkan dinamika populasi manusia dan nyamuk sebagai vektor. Model SEIR digunakan untuk manusia dengan kompartemen Susceptible (S), Expose (E), Infected (I),

A Geometric Interpretation and Comparison of the Methods Of Ordinary Least Square (OLS) and Bivariate Lagrange Interpolation

2015
In this study, the consumer prices, real gross domestic product (GDP) and unemployment for Germany and Turkey between 2006 and 2011 are geometrically interpreted by using Lagrange interpolation and OLS method. The coefficients of linear regression models are obtained by matrix display of OLS method.

BRIDGING ORDINARY LEAST SQUARE (OLS) AND MACHINE LEARNING (RANDOM FOREST REGRESSION): AN EMPIRICAL STUDY OF FISHERIES' CONTRIBUTION TO GDP IN NIGERIA

ABSTRACT This study investigated the contribution of the fisheries subsector to Nigeria’s Gross Domestic Product (GDP) by comparing the performance of an Ordinary Least Squares (OLS) regression model and a Machine Learning Random Forest Regression model.
