Article Introduction：Studentized residuals are often used in regression analysis to identify potential outliers in the data. Outliers are points that differ significantly from the overall trend of the data and can have a significant impact on the fitted model. By identifying and analyzing outliers, you can better understand underlying patterns in your data and improve the accuracy of your models. In this post we will take a closer look at studentized residuals and how to implement it in python. What are studentized residuals? The term "studentized residuals" refers to a specific class of residuals whose standard deviation is divided by the estimate. Regression analysis residuals describe the difference between the observed value of the response variable and its expected value generated by the model. To find outliers in the data that may significantly affect the fitted model, studentized residuals were used. The following formula is commonly used to calculate studentized residuals
