Definition of the logistic function An explanation of logistic regression can begin with an explanation of the standard logistic function. The logistic function is a sigmoid function, which takes any real input $${\displaystyle t}$$, and outputs a value between zero and one. For the logit, this is interpreted as taking input log … See more In statistics, the logistic model (or logit model) is a statistical model that models the probability of an event taking place by having the log-odds for the event be a linear combination of one or more independent variables See more Problem As a simple example, we can use a logistic regression with one explanatory variable and two categories to answer the following question: See more There are various equivalent specifications and interpretations of logistic regression, which fit into different types of more general models, and allow different generalizations.
