The standard logistic function is the logistic function with parameters , , , which yields In practice, due to the nature of the exponential function , it is often sufficient to compute the standard logistic function for over a small range of real numbers, such as a range contained in [−6, +6], as it quickly converges very close to its saturation values of 0 and 1.
