Residual Error In Linear Regression Likewise, the sum of absolute errors (SAE) refers to the sum of the absolute values of the residuals, which is minimized in the least absolute deviations approach to regression. Other uses of the word "error" in statistics[edit] See also: Bias (statistics) The use of the term "error" as discussed in the sections above is in the sense of a deviation However, a terminological difference arises in the expression mean squared error (MSE).
