A sigmoid function is a mathematical function having a characteristic "S"-shaped curve or sigmoid curve. A common example of a sigmoid function is the logistic function shown in the first figure and defined by the formula: Other standard sigmoid functions are given in the Examples section.

The failure rate function r is given by r(z) = kzk − 1 1 + zk, z ∈ (0, ∞) If 0 < k ≤ 1, r is decreasing.

Link created an extension of Wald's theory of sequential analysis to a distribution-free accumulation of random variables until either a positive or negative bound is first equaled or exceeded. Link derives the probability of first equaling or exceeding the positive boundary as , the logistic function. This is the first proof that the logistic function may have a stochastic process as its basis.
