D)Residual sum

Question

Quizplus · Accepted Answer

Plotting residuals in a time-ordered sequence helps to assess the independence assumption. If the residuals show correlation or patterns over time, it indicates that the model does not capture all the relevant information or that the errors are not independent. Normality and constant variation assumptions can be assessed through normal probability plots and plots of residuals against predicted values, respectively. Residual sum is not an assumption but a measure of the difference between actual and predicted values.
