Объясняется это как объективной сложностью самих данных, так и субъективной природой анализирующего их эксперта.Поэтому адекватная формализация этого требует совершенно нового аппарата, с одной стороны способного преодолеть объективную сложность данных (нерегулярность и неточность), а с другой - нечеткий характер суждений эксперта. Развитие Дискретного математического анализа (ДМА) является важным шагом в этом направлении. ДМА значительно ориентирован на эксперта и занимает промежуточное положение в анализе данных междужесткими математическими методами (статистический анализ, СВАН и др.) и мягкими комбинаторными (имитационное моделирование, нейронные сети и др.).В настоящей работе предлагаются новые математические конструкции регрессионных производных и регрессионных интегралов для дискретных временных рядов, заданных вобщем случае на нерегулярной сетке. В их изучение важную роль играет недавно созданный авторами проекционный метод решения систем линейных алгебраических уравнений,описанный в конце работы.Полученные конструкции регрессионных производных и регрессионных интегралов имеют иерархический характер в духе вейвлет- и фрактального анализов.Результаты работы определяют направление для дальнейших исследований, а именно, проникновение регрессионного дифференцирования и регрессионного интегрирования вконечную математику по сценариям классической.</p></abstract><trans-abstract xml:lang="en"><p>Data analysis is a complex and multi-dimensional concept. It is explained by both the objective complexity of the data itself and the subjective nature of the expert analyzing them.Therefore, adequate formalization of this requires a completely new apparatus, on the one hand, capable of overcoming the objective complexity of data (irregularity and inaccuracy),and, on the other hand, the vague nature of expert judgment. The development of Discrete Mathematical Analysis (DMA) is an important step in this direction. DMA is highly expertoriented and occupies an intermediate position in data analysis between strict mathematical methods (statistical analysis, TFA, etc.) and soft combinatorial methods (simulation modeling,neural networks, etc.).This paper proposes new mathematical constructions of regression derivatives and regression integrals for discrete time series defined in general on an irregular grid. An important role in their study is played by the recently created by the authors projection method for solving systems of linear algebraic equations described at the end of this paper.The obtained constructions of regression derivatives and regression integrals have a hierarchical character in the spirit of wavelet and fractal analysis.The results of this work define another direction in further studies, namely, the propagation of regression differentiation and regression integration in finite mathematics under scenarios of the classical one.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дискретный математический анализ</kwd><kwd>регрессионная производная</kwd><kwd>ре- грессионный интеграл</kwd><kwd>ядро оператора</kwd><kwd>неинтегрируемый ряд</kwd></kwd-group><kwd-group xml:lang="en"><kwd>discrete mathematical analysis</kwd><kwd>regression differentiation</kwd><kwd>regression integration</kwd><kwd>operator kernel</kwd><kwd>functional non-integrable series</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках государственного задания Геофизического центра РАН, утвержденного Минобрнауки России</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Mikhailov V., Galdeano A., Diament M., Gvishiani A., Agayan S., Bogoutdinov Sh., Graeva E., and Sailhac P.
