Residuals In Multiple Linear Regression 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
