WebDec 23, 2016 · According to the discussion in Draper and Smith's Applied Regression Analysis (3rd edition, roughly page 59), this residual plot may be used to check for violations in model assumptions particularly related to incorrect specification or presence of heteroscedasticity. Webc) The fanned pattern indicates that the linear model is not appropriate. The model’s predicting power decreases as the values of the explanatory variable increase. 12. Residuals II. a) The curved pattern in the residuals plot indicates that the linear model is not appropriate. The relationship is not linear.
