dynamical system, variable in probability distribution












0














I'm not mathematician... I have a question:



If I have a variable $n$ that can evolve in time. This variable have a probability distribution $D$.



Is there a mathematical "tool" that permit to obtain the expression a differential equation such as for any type of distribution $D$:



$frac{dn}{dt} = f(D,n)$



EDIT :
If I do something like : $frac{dn}{dt} = tau (D-n)$ does it mean that $n$ will follow $D$ at the velocity $tau$ ?

    Are you think of something like Brownian motion or a stock market index. These are covered by stochastic calculus (as in caverac's link).
