Abstarct: The estimation of regression parameters is very important in analysing and predicting data. A common method is the least squares estimator that it does not have good performance in case of multicollinearity, so that the shrinkage estimators were born. One of these most popular techniques is bridge estimator. Also, the least squares and shrinkage estimators are influenced by outliers. Although, there are many papers about these estimators, the suggested methods are not good when the data suffers multicollinearity problem. In this dissertation, we propose a new method called robust bridge that controls the existence outliers and high multicollinearity. Also, the asymptotic behavior of this estimator is studied and the computational algorithm is introduced. As a special case, the robust LASSO and ridge and their fuzzied versions are verified.
