The scatter chart shows patterns in the residuals, indicating that they are not randomly distributed and therefore not independent. This suggests that the model may need further refinement to better capture the relationship between the variables. However, the scatter chart does not provide information on whether the model is time-invariant or whether the residuals are normally distributed.
