| Abstract | ||
| In this paper, the test of unit root for bounded AR (2) model without constant and dependent errors has been derived. Asymptotic distributions of OLS estimators and statistics under different tests of hypotheses have been derived. A simulation study has been established to compare between different tests of the unit root. Mean squared error (MSE) and Thiel's inequality coefficient (Thiel’s U) have been considered as criteria of comparison. | ||
