LINEST performs an ordinary least squares calculation (Wikipedia, 2014b). The least squares process of solving for the slope and intercept for the best fit line is to calculate the sum of squared errors between the line and the data and then minimize that value. In ordinary least squares it is assumed that there are no errors in the x‐values.
