  Instead of using Excel’s prebuilt fitting tool, do it the hard way: The line will be y = ax + b and you need to find a and b. Pick two cells for these coefficients. Build columns with the absolute errors and the squared errors. Use Solver to minimize the sum of the squared errors to find a, the slope and b, the y-intercept. (These should be ...

  SSE stands for “sum of squares due to error” - this is simply the sum of the squared residuals, and it is the variation in the Y variable that remains unexplained after taking into account the variable X. The interpretation of equation (2) is now clear.

  The line created by Excel is called the least-squares line. We minimize the sum of squared errors rather than the sum of the errors because in simply summing the errors, positive and negative errors can cancel each other out. For example, a point 100 units above the line and a point 100 units below the line will cancel each other if we add errors.

  Next, establish a column of squared errors for current, and then one cell with sum of squared errors. Now, under “Tools,” select “Solver.” The following window will appear. Enter your “Target Cell” (the sum of squared errors cell), plus the “Changing Cells” that correspond to Isc, A, and B.
