In this some new estimation methods and testing procedures for the linear regression models with heteroscedastic disturbances. A Minimum Norm Quadratic Unbiased (MINQU) estimation method has been developed for estimating the unknown heteroscedastic error variances by using the weighted studentized residuals. A multiplicative heteroscedastic linear regression model has been specified and a method of estimating the parameters of linear regression model along with the in the heteroscedastic error variance has been given by using the predicted residuals. Three types of modified estimators ...

There is no more striking fact in the history of international relations than that so serious a question should have been treated with such amateurish simplicity as has been the case in the plans for armament reduction." J.T. Shot well "Disarmament should be viewed as a process of creating conditions which make it difficult or impossible for nations to break or endanger the peace not as a bargaining process to reduce the cost of preparing for war." - Benjamin V.
