Witryna3 kwi 2024 · The logistic equation is useful in other situations, too, as it is good for modeling any situation in which limited growth is possible. For instance, it could model the spread of a flu virus through a population contained on a cruise ship, the rate at which a rumor spreads within a small town, or the behavior of an animal population on an … 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.

WitrynaThe logistic growth model relies on a maximum attainable level known as the carrying capacity.
