How Do You Calculate The Sum Of Squares For Error (SSE)?
• SSE shortcut formula Decide which formula to use. While both formulas are correct, the shortcut formula is generally easier to use as it contains values you have probably already calculated. The following steps assume you are using the shortcut formula. • Calculate the covariance of x and y. • Calculate the variance of x. • Calculate the variance of y. Substitute these values into the formula, assuming n = the number of data points in the sample.
