The difference diffusion model with two equilibrium states is given by a stochastic equation with two components: the predicted one, which is determined by the regression function of increments with two equilibriums, and the stochastic one, which is the martingale difference.We propose a classification of zones of influence of equilibriums according to asymptotic properties of trajectories of statistical experiments.We study asymptotic behavior of statistical experiments, determined by the sums of N sample values, as N → ∞.
