(Redirected from S curve) S curve or S-curve can refer to: 1  S Curve (art), an art term for a sinuous body position, noted in ancient marble sculpture. 2  S-Curve Records, a record label.  Sigmoid curve or sigmoid function, a mathematical function that produces a sigmoid, or S-shaped, curve.
A logistic function or logistic curve is a common S shape (sigmoid curve), with equation: where e = the natural logarithm base (also known as Euler's number), x 0 = the x-value of the sigmoid's midpoint,L = the curve's maximum value, and.k = the steepness of the curve. For values of x in the range of real numbers from ââ to +â, the S-curve shown on the right is obtained (with the graph of f approaching L as x approaches +â and approaching zero as x approaches ââ).The function was named in 1844â1845 by Pierre Francois FranÃ§ois, verhulst who studied it in relation to population. growthhe logistic function is the inverse of the natural logit function and so can be used to convert the logarithm of odds into a probability. In mathematicaly notation the logistic function is sometimes written as expit in the same form as logit.
