the interest in forecasting and managing the quality of metal based on data mining using special software products often based on regression analysis and not always taking into account the statistical nature of an object of study itself. This can lead to misinterpretation of the results or incomplete extracted information reducing the efficiency of statistical processing. Based on the analysis of the production database of the technology for producing 13G1S-U sheet steel, the authors evaluated the possibilities of multiple linear regression for predicting the quality of a steel sheet. The study shows that the type of distribution of the values of control parameters, the distribution nature of which was estimated based on the determination of the skewness and kurtosis coefficients, limits the regression forecast depth. Due to the great deviation of the predicted models from the experimental values in the right tail area of the distribution of the impact strength values, in this work, the authors developed the methods for separating data arrays and proposed criteria to compare the obtained results. To assess the accuracy of the results obtained, arrays with a deliberately asymmetric distribution were selected from the initial sample, against which the statistical characteristics were also compared. Based on the proposed techniques, the authors identified the dominant chemical elements that contribute to the difference in the distribution of the values of acceptance properties existing within the same standard technology. The study shows that the proposed separation method can be used as a variation of cognitive graphics techniques to identify areas with a dependence dominant type based on the correlation of skewness and kurtosis coefficients.</p></abstract><trans-abstract xml:lang="ru"><p>Формирование представительных баз данных определяет интерес к прогнозированию и управлению качеством металла на основе раскопок данных с использованием специальных программных продуктов, зачастую основанных на регрессионном анализе и не всегда учитывающих статистическую природу самого объекта исследования. Это может привести к ошибочной трактовке результатов или к неполноте извлекаемой информации, снижая эффективность статистической обработки.<italic> </italic>На основе анализа производственной базы данных технологии получения листовой стали 13Г1С-У были оценены возможности множественной линейной регрессии для прогноза качества листа. Показано, что глубина прогноза регрессии ограничена видом распределения значений управляющих параметров, характер распределения которых оценивали на основе определения коэффициентов асимметрии и эксцесса. В связи с сильным отклонением прогнозируемых моделей от экспериментальных значений в области правого хвоста распределений значений ударной вязкости, в данной работе были развиты методы разделения массивов данных и предложены критерии сравнения получаемых результатов. Для оценки корректности получаемых результатов из исходной выборки были выделены массивы с заведомо ассиметричным распределением, относительно которых также проведено сравнение статистических характеристик. На основе предлагаемых методов выявлены доминирующие химические элементы, которые вносят вклад в различие распределения значений приемо-сдаточных свойств, существующих в рамках одной и той же штатной технологии. Показано, что предложенный метод разделения может быть использован как вариация приемов когнитивной графики для выделения областей с доминирующим типом зависимости на основе соотношения коэффициентов асимметрии и эксцесса.</p></trans-abstract><kwd-group xml:lang="en"><kwd>analysis of production control data</kwd><kwd>metal product quality control</kwd><kwd>quality forecast in metallurgy</kwd><kwd>cognitive graphics techniques</kwd><kwd>production data mining</kwd><kwd>13G1S-U steel</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>анализ данных производственного контроля</kwd><kwd>управление качеством металлопродукции</kwd><kwd>прогноз качества в металлургии</kwd><kwd>приемы когнитивной графики</kwd><kwd>раскопки производственных данных</kwd><kwd>сталь 13Г1С-У</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Vyboyshchik M.A., Ioffe A.V.
