Since heteroscedasticity in error terms cause inefficient parameter estimation, it should be tested before data analysis. The objective of this paper is to present five widely used likelihood based constructive heteroscedasticity tests which are the ordinary likelihood ratio test, the conditional likelihood ratio test, the corrected modified likelihood ratio test, the modified likelihood ratio test, the profile likelihood ratio test and the residual likelihood ratio test. Also simulation study is performed to compare these tests. CR - Amemiya, T. (1977), “A Note on a Heteroscedastic Model”, Journal of Econometrics, 6, 365-370.
