Using the Weighted Average of Rounded Points to Estimate 〖CO〗_2 Emissions

Abstract

In this article, the weighted average of the rounded points (WARPing) is used to estimate the carbon dioxide 〖CO〗_2 in Iraq with Nadaraya-Watson and Local Linear estimators for the period (1990-2019). The results proved the superiority of the Local Linear estimator, especially at the boundary points, despite the good and equal performance of the Nadaraya-Watson with Local Linear in the interior points except for the boundary points which showed the powerless of this method.
