Abstract

Estimation methods are an important cornerstone of regression analysis, and based on an accurate model will result in a well-represented analysis. In this study, a comparison was made between the two methods of maximum likelyhood and the least absolute deviation. Thi Qar for the year 2018. two criteria were used for the differentiation between the models, , the criterion of the coefficient of determination  and the criterion of the mean squares error (MSE). The maximum likelihood method is better than the less absolute deviation method
