- FitLogistic( <List of Points> )
- Calculates the regression curve in the form a/(1 + b e^(-kx)).
- Example:
FitLogistic({(-6, 2), (0, 2), (3, 4), (3.4, 8)})
yields \frac{1.98}{1 - 0.03 e^{1x}}.
Note:
- The first and last data points should be fairly close to the curve. The list should have at least 3 points, preferably more.
- See also Fit, FitExp, FitGrowth, FitLine, FitLineX, FitLog, FitPoly, FitPow and FitSin.
- If you work with big/small numbers, you should consider normalizing them for a more accurate result, see Normalize Command.
