Fitting simple linear equationsĮxcel provides us with a couple of tools to perform Least SquaresĬalculations, but they are all centered around the simpler functions: Method here, just read up on the matter by clicking that link to Perhaps you did some measurements with results like this:Ī well known way to fit data to an equation is by using the If you're a properĮngineer, you also have some idea what type of equation should Way to fit your measurement results with a curve.
