• Inadequate data preparation

To learn more about residual calculation and how to apply it in your field, consider the following resources:

Residuals are the differences between observed and predicted values in a dataset. To calculate residuals, you need to follow these basic steps:

How Residual Calculation Works

• Enhanced prediction capabilities
• Myth: Residuals are only useful for identifying outliers.

Residual plots help identify patterns and anomalies in the data. A random scatter of residuals indicates a good fit, while a non-random pattern may indicate a need for model refinement.
