Calculate mean squared error for four prediction residuals. The page evaluates the displayed equation from your supplied values and presents both symbolic and substituted KaTeX working so the arithmetic can be checked.
MSE=sum(e_i^2)/4

Use boundary
Residuals use one outcome scale and each observation receives equal weight.
Use internally consistent units and retain extra precision when carrying the result into another calculation.
