Abstract
The distribution function of the local order parameter in finite blocks of size is studied for Ising models for dimensionalities by Monte Carlo methods. A real-space renormalization group based on phenomenological scaling yields fairly accurate results for rather small (e.g., the standard exponents and for are found as , ). The method can easily be generalized to arbitrary Hamiltonians, including spin dimensionalities .
