Рассматриваются аспекты разделения событий на однородные группы на основе количественных методов. Проводится качественное исследование влияния формирования выборок на итоговые оценки. В трех вариантах формулируется задача совмещения наборов данных с разными порогами отсечения. Предлагается алгоритм для решения задачи совмещения данных с разными порогами отсечения на основе усеченных распределений. Исследуется вопрос о недостатке данных для калибровки моделей оценки операционного риска. Обсуждаются три подхода к экстраполяции за пределы имеющихся данных с учетом потенциального наличия экстремальных потерь. В заключении статьи авторы приводят возможные пути решения проблемы малого количества данных об операционных потерях, направленные «снизу» и «сверху».</p></abstract><trans-abstract xml:lang="en"><p>In this paper, authors consider several particular problems regarding data samples for operational risk assessment models calibration. This study analyzes some aspects of data partition into homogeneous groups. It holds qualitative analysis of grouping structure influence on resulting estimates. Further, it formulates three variants of the different threshold data mixing problem and then the algorithm of solving that data mixing problem is being proposed. As a result, authors raise the question of sufficiency of operational risk data for the model calibration. They consider three approaches to extrapolation beyond the data sample regarding the presence of extremal severity events. The conclusion of the paper points at the lack of operational loss data. In addition, authors suggest several ways of solving this problem.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>операционный риск</kwd><kwd>Базель II</kwd><kwd>внешние данные</kwd><kwd>калибровка модели LDA</kwd></kwd-group><kwd-group xml:lang="en"><kwd>operational risk</kwd><kwd>Basel II</kwd><kwd>external data</kwd><kwd>LDA model calibration</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">Золотарева Е.Л.
