Let us consider an odds ratio, which is defined as Ω = π/ (1-π) where 0 < Ω < ∞ and π is the probability of success. Here, let π = E (Y X) and then you will notice that and so we have range (-∞, ∞). nanowrimo sign inWebWhen a function’s variable represents a probability, p (as in the function above), it’s called the logit function .

"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. The logistic function has the symmetry property that " - Is a logistic function odd
