We can associate with the voting process, a function V
Each person is described by a set of attributes
age, income, place
they live, etc.
with a big enough size vector
Each person a particular vector.
If we were mathematicians, we could find from survey (determine parameters in it) and so predict
election result.
But society is a ``complex system.'' Impossible to write down some
function V even though actions might be described by some sort of
function.
use probabilistic approach.
