Sustainability in 19 different Arab countries has been studied through investigating the relationship between economic development and energy consumption. Data collected has been studied as a whole (Total countries data) and as segregated data (Oil exporting and Oil importing countries data) i.e. three categories. The regression model used measures the effect of independent and control variable...

in a structural time series regression model, binary variables have been used to quantify qualitative or categorical quantitative events such as politic and economic structural breaks, regions, age groups and etc. the use of the binary dummy variables is not reasonable because the effect of an event decreases (increases) gradually over time not at once. the simple and basic idea in this paper i...

This paper addresses the following question: can satisfactory residential property price indexes be constructed using hedonic regression techniques where location effects are modeled local neighborhood dummy variables or is it necessary to use spatial coordinates model effects. Hill and Scholz (2018) addressed this question found, their model, that was not obtain for Sydney. However, did estima...

The authors of the published article have identified issues with the analysis which raise concerns about the conclusions of this paper. When conducting the analysis, some of the country dummy variables were incorrectly generated in Excel prior to analysis in R. When the dummy variables are correctly generated, they substantially changed the shape of the partial residual plots such that the conc...
