Finally, ULFR model will be applied to find error-free efficiency.
(2007) utilized ULFR model to find error value from dependent and independent variables' simple linear regression: as conventional regression models are not suitable for global versus localized measure, perfect reference and bivariate case.
Most importantly, no article is recognized that shows the error-free technical efficiency by applying ULFR model.
Hussin (1997) defined the model (9) and (10) as the unreplicated linear functional relationship (ULFR) model when there is only the variables EF(CDS) and PR.
And the coefficient of determination of ULFR ([R.sup.2].sub.f]) for any value of [lambda]:
