Sass, M. E. (Mary Ellen)

Abstract:

Essential to the testing of propositions in economic theory is the estimation of the parameters involved in relationships among economic variables. Probably the most widely used method of estimation is ordinary least squares (OLS). However, severe multicollinearity or near linear dependence of the explanatory variables can cause the OLS estimates...
