Uncovering Hidden Patterns: Calculating Residuals 101 - em
Calculating residuals is a straightforward process that involves identifying the difference between observed and predicted values. In essence, residuals are the errors or discrepancies between the actual data and the model's predictions. By calculating residuals, you can identify patterns, trends, and anomalies in your data that may not be immediately apparent. There are several types of residuals, including:
Residuals are used in various statistical models, including linear regression, logistic regression, and time series analysis.
