The primary purpose of residuals is to evaluate the accuracy of a statistical model. By examining the residuals, analysts can identify potential issues with the model, such as outliers, non-linear relationships, or inadequate data.
Common Questions About Residuals
Residuals are the difference between the observed and predicted values in a statistical model. They are a measure of the model's ability to explain the variability in the data. When residuals are small, it indicates that the model is doing a good job of capturing the underlying patterns in the data. Conversely, large residuals suggest that the model may not be capturing the underlying relationships, indicating potential issues with the model.
