Abstract This study investigates the influence of democracy, autocracy, and globalization on carbon dioxide (CO 2 ) emissions in 69 developing countries from 1990 to 2018. We used unit root approaches scrutinize level stationarity recognize that all concern variables were unified at first difference.

Ordinary differential equations (ODEs) are widely used in biomedical research and other scientific areas to model complex dynamic systems. It is an important statistical problem to estimate parameters in ODEs from noisy observations. In this article we propose a method for estimating the time-varying coefficients in an ODE. Our method is a variation of the nonlinear least squares where penalize...

Ordinary least squares is unlikely to estimate growth regressions consistently. A simple alternative method is formulated. Applying ordinary least squares and this method to data on 85 countries over the period 1964-1990 reveals that ordinary least squares is strongly biased. The consistent estimates are about twice as large in magnitude as the inconsistent estimates. This finding suggests that...

Using simulation, I evaluated five regression procedures that are used for analyzing methods comparison data: ordinary least-squares regression analysis, weighted least-squares regression analysis, the Deming method, a weighted modification of the Deming method, and a rank procedure. I recorded the following performance measures: plus or minus bias of the slope estimate, the root mean squared e...

This study aims to test the validity of tourism-led growth hypothesis. For this purpose, ten countries with highest tourism income (USA, China, Australia, France, Italy, England, Spain, Germany, Japan, Thailand) are included in analysis covering period 1995-2018. Pedroni cointegration, panel Dynamic Ordinary Least Square (DOLS) and Fully Modified (FMOLS) methods utilized by using economic growt...

We consider the least-squares finite element method (lsfem) for systems of nonlinear ordinary differential equations, and establish an optimal error estimate this when piecewise linear elements are used. The main assumptions that vector field is sufficiently smooth local Lipschitz constant as well operator norm Jacobian matrix associated with nonlinearity small, restricted to a suitable neighbo...

recently, in order to increase the efficiency of least squares method in numerical solution of ill-posed problems, the chain least squares method is presented in a recurrent process by babolian et al. despite the fact that the given method has many advantages in terms of accuracy and stability, it does not have any stopping criterion and has high computational cost. in this article, the attempt...
