S-curve function

WebbCurve fitting is the process of constructing a curve, or mathematical function, that has the best fit to a series of data points, possibly subject to constraints. [4] [5] Curve fitting can involve either interpolation , [6] [7] where an exact fit to the data is required, or smoothing , [8] [9] in which a "smooth" function is constructed that approximately fits the data.
