Web9 Apr 2015 · Use the least squares method to fit a line for your points. You are basically looking for a function y=f (x) which fits best. Once you have it you can use the actual y values to sum the square of differences: s = sum over ( (y-f (x))^2 ) The smaller the sum, the straighter the line.
