Первый (интегральный) метод связан с соответствующим изменением функции правдоподобия. Второй (resampling) метод восстановления отказов основан на итерационном восстановлении моментов отказов. Исследованы точности предложенных методов оценивания.</p></abstract><trans-abstract xml:lang="en"><p>The paper offers two modifications of the nonparametric root estimation of a density function in case of incomplete data in the form of grouped frequencies of failures. The first (integrated) method is connected with respective alteration of a likelihood function. The second (resampling) method of the restoration of failures is based on the iterative restoration of failure time points. The accuracy of the offered estimation methods has been investigated.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>пси-функция</kwd><kwd>метод квадратного корня</kwd><kwd>функция правдоподобия</kwd><kwd>псевдоотказы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>psi-function</kwd><kwd>square-root method</kwd><kwd>likelihood function</kwd><kwd>pseudo-failures</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">Антонов А.В., Чепурко В.А.
