Logistic function
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),
  • x0 = the x-value of the sigmoid's midpoint,
  • L = the curve's maximum value, and
  • k = the steepness of the curve.
