However, a terminological difference arises in the expression mean squared error (MSE). The mean squared error of a regression is a number computed from the sum of squares of the computed residuals, and not of the unobservable errors. If that sum of squares is divided by n, the number of observations, the result is the mean of the squared residuals.
Percent error is used when you are comparing your result to a known  or accepted value. It is the absolute value of the difference of  the values divided by the accepted valâ¦ue, and written as a  percentage. Percent error is equal to the difference divided by the  known times 100 percent.
