As it says in the title, will anyone please give me the equation (in pre-algebraic terms) for discrete choice probability? I can see that the equation is P = Prob( Person n chooses Alternative i ) = G(x(adsbygoogle = window.adsbygoogle || []).push({}); _{ni}, x_{nj}(forall j inequal to i), sn, β),

where

x_{ni}is a vector of attributes of alternative i faced by person n,

"forall j inequal to i" is a vector of attributes of the other alternatives (other than i) faced by person n,

sn is a vector of characteristics of person n, and

β is a set of parameters that relate variables to probabilities, which are estimated statistically.

(I'm totally copying this off Wikipedia.) I'm baffled. What is G()?
