| 1. | In 1973, Huber introduced explanatory variables ( leverage points ).
|
| 2. | The dependent variable is Y . There is an explanatory variable X1.
|
| 3. | A construct is a hypothetical explanatory variable that is not directly observable.
|
| 4. | The explanatory variables were white population in the period studied.
|
| 5. | For a continuous explanatory variable, the same interpretation applies to a unit difference.
|
| 6. | Also, the range of the explanatory variables defines the information available from them.
|
| 7. | This scheme has the advantage that it retains the information in the explanatory variables.
|
| 8. | The unobserved effects means that one or some of the explanatory variables are unobservable.
|
| 9. | The case of one explanatory variable is called " simple linear regression ".
|
| 10. | Regression analysis controls for other relevant variables by including them as regressors ( explanatory variables ).
