Logit

operatorname logit(p)= log (p/(1-p))= log (p)- log (1-p).!,

The relation of the logit formula to the distribution of unobserved utility (as opposed to the characteristics of choice probabilities) was developed by Marley, as cited by Luce and Suppes (1965), who showed that the extreme value distribution leads to the logit formula.

Improvements in computer speed and in our understanding of simulation methods have allowed the full power of mixed logits to be utilized.
