How to calculate standardized residuals?
Understand the Problem
The question is asking for the method to calculate standardized residuals, which are used in statistical analysis to assess how far observations deviate from the fitted model in standard deviation units.
Answer
Raw residual divided by the standard deviation of the residuals.
The final answer is the standardized residual, which is the raw residual divided by the estimate of the standard deviation of the residuals.
Answer for screen readers
The final answer is the standardized residual, which is the raw residual divided by the estimate of the standard deviation of the residuals.
More Information
Standardized residuals are important in regression analysis to check for outliers or points that have a significant influence on the results.
Tips
Make sure to use the correct standard deviation (or standard error) estimate. Mistakes often occur by using the wrong figure.
