In multiple regression analysis,residuals (Y −  )are used to ________.
A)provide a global test of a multiple regression model 
B)evaluate multicollinearity 
C)evaluate homoscedasticity 
D)compare two regression coefficients

Quizplus · Accepted Answer

Residuals are used to evaluate homoscedasticity, which refers to the equal distribution of errors (residuals) across all values of the independent variable(s). If the residuals are not homoscedastic, the model may not be a good fit for the data.
