Для построения оценки сначала выбирается метрика на пространстве последовательностей. Эта метрика строится по матрице, которую можно интерпретировать как реберную раскраску полного графа с петлями. Обобщение состоит в том, что вместо логарифма в оценке энтропии применяется похожая функция, которая может быть произвольной на заданном интервале. Предлагаемая функция не является монотонной, поэтому задача оптимизации среднего отклонения, которая является задачей квадратичной оптимизации, решается на всем пространстве, а не на симплексе. Основные свойства оценки, такие как, асимптотическая несмещенность и степенное убывание дисперсии, доказываются аналогичным образом.</p></abstract><trans-abstract xml:lang="en"><p>The paper proposes a generalization of entropy as in [<xref ref-type="bibr" rid="cit1">1</xref>]. At first, to constract the estimator, we select the metrics on the space of sequances. This metrics is based on a matrix that can be interpreted as an edge coloring of a complete graph with loops. A generalization consists in that instead of using the logarithm in the estimation of the entropy, we apply a similar function which may be arbitrary at the given range. The proposed function is not monotone, so the task of optimizing the average deviation which is a quadratic optimization problem, is solved in the whole space and not on the simplex. The main properties of the estimator, such as asymptotic unbiasedness and power decrease dispersion, are proved in a similar way.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>энтропия</kwd><kwd>непараметрическая оценка</kwd><kwd>смещение</kwd><kwd>метрика</kwd><kwd>оптимизация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>entropy</kwd><kwd>nonparametric</kwd><kwd>optimization</kwd><kwd>bias</kwd><kwd>metrics</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Timofeev E.A.
