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}}.

CAS Syntax

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}}.
