Proceedings of the National Aviation University, 1998 Показано, что нижняя граница Крамера-Рао для статистических оценок изменена, если алгоритмы оценивания строятся с учетом априорных связей между оцениваемыми величинами и остаточные дисперсии могут быть существенно уменьшены. Рассмотрен случай оценки двух параметров, между которыми существует линейная алгебраическая априорная связь.
