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^x}.

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^x}.

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.
