# Commonly-used Predictor Function?

I was recently taking a look at some political projections (similar to the ones published by 538), and I am wondering about a particular function used to calculate the likelihood of a given party winning a political district. The function $$F(p)$$, defined as $$F(p) = \frac{1}{1 + e^{-0.2809 \cdot p}},$$ where $$p \in [-100,100]$$ is the Cook's PVI. Is this type of function – that is, one of the form $$f(x) = \frac{1}{1+e^{cx}}$$ – commonly used for predicting outcomes like this?
