استعمال طريقة الإمكان الأعظم مع وزن مقترح لتقدير تأثير بعض الملوثات في نهر دجلة-مدينة الكوت

Abstract EN

The aim of this research is to use the method of pruning immunity, as often the analysisof the greatest potential (ML) completely fails if there are abnormal values in thephenomenon studied.

MLE will lose its properties because of the bad effect of the outlierson the studied phenomenon.

Acceptability and optimization, however, weights can beused that increase the efficiency of the resulting capabilities and increase the power ofestimation using the MWTL.

In order to achieve this research, it was necessary to detectand investigate the impact of pollution of the Tigris River water in Kut city due towastewater, especially pollution with water insoluble solids (TDS) as a response variableand the effect of three pollutants (PO4, CL, SO4) as illustrative variables.

This waspresented by statistical research and evaluated accurately and submitted to the competentauthorities, where a sample size (91) was withdrawn and examined in the laboratory ofthe Directorate of sewage in the city of Kut and the analysis was conducted using theprogram MATLAB-2015)).

The differentiation criterion was the RMSE.
