In some of statistical studies which have multivariate Linear regression model, it will be studying independents variables haven't significant effect on the dependent variable, and can delete them from the model.

There are many methods to detect optimal multiple linear regression model have important independent variables, But firstly we must treat problems of linear regression to getting best results.

In this paper will been study one of an important disease called (Hepatitis Disease) which represent an dependent variable, where detected it depending on (4) tests called (G.O.T, G.P.T, T.S.B, Aik) which represent independent variables, and for several sample size, and will test problems of multiple linear regression and then test effect of this variables to detect the disease.
