WebNov 26, 2024 · Scattered Data Spline Fitting Example in Python Interpolation is a method of estimating unknown data points in a given range. Spline interpolation is a type of piecewise polynomial interpolation method. Spline interpolation is a useful method in smoothing the curve or surface data. WebThe generalized Logistic model (also known as Richards’ curve) is an extension of the logistic or sigmoid functions, allowing for more flexible S-shaped curves: log ( N t) = A + K − A 1 + Q ( e − B t) 1 / μ. Where A is the lower asymptote, K is the higher asymptote. If A = 0 then K is the carrying capacity.
