The most common residual plot shows ŷ on the horizontal axis and the residuals on the vertical axis. Graphical plots and statistical tests concerning the residuals are examined carefully by statisticians, and judgments are made based on these examinations. Good judgment and experience play key roles in residual analysis. As such, they are used by statisticians to validate the assumptions concerning ε. These residuals, computed from the available data, are treated as estimates of the model error, ε. The i th residual is the difference between the observed value of the dependent variable, y i, and the value predicted by the estimated regression equation, ŷ i. Since the statistical tests for significance are also based on these assumptions, the conclusions resulting from these significance tests are called into question if the assumptions regarding ε are not satisfied. If the error term in the regression model satisfies the four assumptions noted earlier, then the model is considered valid. The analysis of residuals plays an important role in validating the regression model.
