Comparison of some robust estimators of parameters of nonlinear models

Abstract

The robust estimations of parameters for any models taken large interest in the last period but the most searches was for linear models. The importance of this study is coming because the most actuality experiments represented by nonlinear models where its deals with M method which its used for robust estimation of linear models and how its used for nonlinear models and suggested two statistics used in M method for nonlinear models .So the search explained how to used L1-norm method to robust estimating the parameters of nonlinear models.The comparison between the studies methods and the classic OLS method which is used for nonlinear models is doing by simulation where simulated four samples size.
