- FitExp( <List of Points> )
- Calculates the exponential regression curve in the form aℯbx.
- Example:
FitExp({(0, 1), (2, 3), (4, 3), (6, 4)})
yields 1.31ℯ0.21x.
Note:
- If you want the answer in the form a b ^ x then use the FitGrowth Command.
- You can do a direct least-squares fitting with
Fit(list, a*exp(b*x))
- Euler's number ℯ can be obtained by pressing ALT + e.
- See also Fit, FitGrowth, FitLine, FitLineX, FitLog, FitLogistic, FitPoly, FitPow and FitSin.
