Assume that in a particular multiple regression model, it is determined that the error terms are uncorrelated with each other. Which of the following statements is most accurate? A. Serial correlation may be present in this multiple regression model, and can be confirmed only through a Durbin-Watson test. B. Multicollinearity exists in this multiple regression model, and can be corrected through the addition of a correlated variable. C. This model is in accordance with the basic assumptions of multiple regression analysis because the errors are not serially correlated. D. Unconditional heteroskedasticity present in this model should not pose a problem, but can be corrected by using robust standard errors. |
