Description: The article cited research and forecasting analysis unauthorized access at relatively extreme formulation of the problem. It is proved that the optimal structure conventionally extreme consistent rules similar to that of Bayesian rules. Determined that the best rule is to compare statistics with two constant over time thresholds. We prove asymptotic optimality in the proposed rule is not only independent of similar observations, but for some types of correlated observations in heterogeneous unbalanced situation.
