| 1. | We reject the null hypothesis of homoscedasticity and conclude that heteroscedasticity is present.
|
| 2. | Thus heteroscedasticity is the absence of homoscedasticity.
|
| 3. | However, it has been said that students in econometrics should not overreact to heteroscedasticity.
|
| 4. | He is known for his contributions to the development of heteroscedasticity-consistent standard errors.
|
| 5. | He is known for his contributions in the development of heteroscedasticity-consistent standard errors.
|
| 6. | The model is the same as normal, which allows any pattern of correlation and heteroscedasticity:
|
| 7. | Generally, when testing for heteroscedasticity in econometric models, the best test is the White test.
|
| 8. | Heteroscedasticity-consistent standard errors are used to allow the fitting of a model that does contain heteroscedastic residuals.
|
| 9. | This validates the use of hypothesis testing using OLS estimators and White's variance-covariance estimator under heteroscedasticity.
|
| 10. | In regression analysis, " heteroscedasticity " refers to unequal variances of the random error terms ? i, such that
