Thesis (Ph.D.) - Cairo University - Institute of Statistical Studies and Research - Department of Statistics and Econometrics

The thesis contains two parties, the first part of the thesis presents five new estimators to solve the problem of multicollinarity and outliers in SUR model, solve the problem of multicollinarity and outliers under exact restriction. The second part of the thesis adds the stochastic restricting as a condition to robust, ridge and robust ridge estimators to get stochastic restriction for general SUR robust, ridge and robust ridge estimator
