Logistic function wikipedia

Logistical activities can be divided into three main areas, namely order processing, inventory management, and freight transportation. Traditionally, order processing was a time-consuming activity that can take up to 70% of the order-cycle time. However, with the advent of new technologies such as bar code scanning, computers, and network connection, orders from customers can quickly reach the seller in no time and the availability of stocks can be checked i… WitrynaThe logistic function is the inverse of the natural logitfunction and so can be used to convert the logarithm of oddsinto a probability. In mathematical notation the logistic function is sometimes written as expit[4]in the same form as logit. The conversion from the log-likelihood ratioof two alternatives also takes the form of a logistic curve.
