For non-linear interpolation, Excel does not have a built-in function, but you can use other functions like TREND, GROWTH, or LINEST to perform various types of curve fitting and extrapolation. 2. What are the differences between extrapolation and interpolation? Answer: Interpolation is the ...
The Microsoft Excel 'Solver' tool is a very simple but powerful procedure, even in the hands of the mathematically disadvantaged. It has very good application for quickly fitting experimental flow-curve data to non-Newtonian flow models with any number of parameters, and can cope with data from...

Summary Excel provides several ways to find the coefficients that provide the best fit of a function to a set of data points — a process sometimes referred to as curve fitting . The "best fit" of the curve is considered to be found when the sum of the squares of the deviations of the...

Why You Need to Fit Curves in a Regression Model The fitted line plot below illustrates the problem of using a linear relationship to fit a curved relationship. The R-squared is high, but the model is clearly inadequate. You need to do curve fitting!
This can be solved in an number of ways. Excel has a LINEST function that can do non linear fitting. For sonething as simple as what you are doing this should be enough and you probably already have Excel. I think the LINEST function is an add in. SciLab has a Levenberg-Marquardt ...
