This study aims to examine the link between inequality and diffusion of Information and Communications Technology (ICT). It focuses on a set of 32 African countries. ICT diffusion rate for all the countries was calculated. Two estimation techniques were used: Fractional Regression Model method and Ordinary Least Squares. The results indicate that inequality contributed to the development of ICT...

The Persian Gulf States (Bahrain. Iran, Iraq, Kuwait, Qatar, Saudi Arabia and United Arab Emirate) have dominated the oil and gas sector since the discovery of oil in the region. They are the world largest producers of crude oil, producing about 35 and 25 percent of the world natural gas and crude oil respectively. The use of fossil fuels is directly linked to the release of CO2 into...

this study analyzed the performance of cabbage marketing in abia state, nigeria. specifically the study sought to: describe socio-economic characteristics of cabbage marketers; identify marketing channels of cabbage; determine marketing cost components of cabbage marketers; determine marketing margins, market share and marketing efficiency of cabbage marketers; and determine socio-economic fact...

A censored variable has a large fraction of observations at the minimum or maximum. Because the censored variable is not observed over its entire range ordinary estimates of the mean and variance of a censored variable will be biased. Ordinary least squares (OLS) estimates of its regression on a set of explanatory variables will also be biased. These estimates are not consistent, i.e., the bias...

This paper explores the correlates of career satisfaction among Canadian managers, professionals and executives, specifically the career satisfaction experience of both visible minority and non-visible minority immigrants. Survey data collected from over 13,000 managers, professionals and executives in 43 Canadian organizations were analysed using the ordinary least squares multiple regression ...

This paper demonstrates that the randomization-based “Neyman” and constanteffects estimators for the variance of estimated average treatment effects are equivalent to a variant of White’s “heteroskedasticity-robust” estimator and the homoskedastic ordinary least squares (OLS) estimator, respectively.

This paper deals with the design and identification of the dynamic model of a compactor, an articulated frame steering mobile engine for use in road construction. A classical approach based on an Ordinary Least Squares identification method is used. A survey of these techniques is given and applied to estimate dynamic parameters of the compactor, and especially the contribution of the contact s...
