Abstract :
Criteria for Testing linear restrictions on parameters in linear statistical models with the heteroscedastic errors have been developed in the present study. A simple test procedure has been suggested to test the linear restrictions in the linear regression models after making a pre-test for the error variance. Some existing tests for general linear hypotheses have been modified with reference to the linear statistical model under the problem of hetroscedasticity.
