In (5), data with no clear trend were assigned a line with a large trend simply due to one outlier (!). Figure 7.4. 1: Six plots, each with a least squares line and residual plot. WebThe good thing about standardized residuals is that they quantify how large the residuals are in standard deviation units, and therefore can be easily used to identify outliers: An observation with a standardized residual that is larger than 3 (in absolute value) is deemed by some to be an outlier.
