Determine the applicable range of concentrations, decide how close the fit must be, and see if you can derive a formula that fits within an acceptable limit. If someone out there has a better theoretical grasp, please answer. | |
| Mar 1, 2015 at 18:35 | comment | added | user1997744 | That's not the problem; I have Mathematica that is capable of fitting any function to a curve, and determining the parameters. My point is that several functions may fit. I'd like a theory which derives or motivates a function, so that my choice of function is justified. | |
| Mar 1, 2015 at 18:34 | comment | added | DrMoishe Pippik | There are many tools to derive a formula to fit a curve. E.G. using Excel (cpp.edu/~seskandari/documents/Curve_Fitting_William_Lee.pdf), or MATLAB, online in Wolfram using it's Fit language (reference.wolfram.com/language/tutorial/CurveFitting.html), or this Regression Fitter (had2know.com/academics/…) | |
| Mar 1, 2015 at 18:27 | comment | added | user1997744 | Yes, all of this is clear. The problem is finding a function to fit to the curve. Is there a more sophisticated theory that suggests a function, rather than I having to guess? Because there are many that can fit the curve 'decently.' | |
