In regression analysis the _________ is used to identify outliers with respect to their x values and ________ is used to identify outliers with respect to their y values.
A)Leverage value,Durbin-Watson statistic
B)Leverage value,residuals
C)Residuals,standardized residuals
D)Durbin-Watson statistic,residuals
E)Variance Inflation Factor,Leverage value

Quizplus · Accepted Answer

The leverage value is used to identify outliers that are extreme in terms of their x values, while residuals are used to identify outliers that are extreme in terms of their y values. Therefore, the best choice is B, leverage value and residuals. The other choices are incorrect, as the Durbin-Watson statistic is used to test for autocorrelation in the residuals, standardized residuals are used to assess the normality of the residuals, and the variance inflation factor is used to test for multicollinearity among the predictor variables.
