Logit

Built-in function new to Analytica 4.5. Before that, supplied as a function in the Generalized Regression library.

Logit(p)

The Logit function is equal to

[math]\displaystyle{ Logit(p) = \ln\left( p\over{1-p} \right) }[/math]

where [math]\displaystyle{ 0\lt p\lt 1 }[/math].

The inverse of the Logit function is Sigmoid(x) (before Analytica 4.5, the function InvLogit was used, defined in the 'Generalized Regression library). The logit function is sometimes called the log-odds function.
