Analysis of residuals involves plotting the residuals (the difference between observed and predicted values) against the predicted values. A scatter plot of the residuals should show no pattern, indicating that the model is a good fit for the data. If there is a discernible pattern, such as a curved line or a funnel shape, this suggests that the model is not a good fit and further investigation may be needed.
