Are Residuals And Errors The Same Thing Regressions In regression analysis the distinction between errors and residuals is subtle and important and leads to the concept of studentized residuals
A residual is the vertical distance between a data point and the regression line Each data point has one residual Definition examples How to define residuals and examine residual plots to assess fit of linear regression model to data being analyzed Includes residual analysis video

Residuals By Jim Frost 171 Back to Glossary Index In statistical models a residual is the difference between the observed value and the mean value that the model predicts for that observation The residuals are the red line segments referenced by the letter quot D quot for distance vertically connecting the scatter plot points to the corrdinating points on the linear regression line You
