Предложен новый подход для повышения точности в задачах построения функции плотности вероятности и оценки её погрешности. Метод основан на использовании экстраполяции Ричардсона и правила Рунге для ядерных оценок с различными параметрами сглаживания. Показано, что применение правила Рунге позволяет оценить погрешность ядерных оценок для функции плотности вероятности и значение её второй производной.</p></abstract><trans-abstract xml:lang="en"><p>The article studies the properties of empirical data under random uncertainty. A new approach is proposed to improve the accuracy in problems of constructing the probability density function and estimating its error. The method is based on the application of Richardson extrapolation and the Runge rule for kernel estimates with different smoothing parameters. It is shown that the application of the Runge rule makes it possible to estimate the error of kernel estimates for the probability density function and the values of its second derivative.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ядерные оценки</kwd><kwd>повышение точности</kwd><kwd>экстраполяция Ричардсона</kwd><kwd>правило Рунге</kwd><kwd>оценки производных функции плотности вероятности</kwd><kwd>kernel estimates</kwd><kwd>improving accuracy Richardson extrapolation</kwd><kwd>Runge rule</kwd><kwd>estimates of the derivatives of the probability density function</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">Тарасенко Ф.
