Разработка алгоритмического способа оценивания параметров линейной регрессионной модели, основанного на минимизации суммы превышений абсолютных отклонений вычисленных значений зависимой переменной от реальных относительно некоторого наперед заданного уровня.</p></sec><sec><title>Методы</title><p>Методы. В качестве базового метода идентификации неизвестных параметров регрессионного уравнения используется метод наименьших модулей, основанный на минимизации городского (манхэттенского) расстояния между векторами расчетных и заданных значений зависимой переменной. Реализация метода сводится к задаче линейного программирования. К ней же путем введения некоторых дополнительных ограничений и замены целевой функции сводится задача минимизации суммы превышений абсолютных отклонений вычисленных значений зависимой переменной от реальных относительно некоторого наперед заданного уровня.</p></sec><sec><title>Результат</title><p>Результат. Построены три альтернативных, с высокой адекватностью, варианта регрессионной однофакторной модели развития отрасли промышленности России, занимающейся производством электрооборудования, электронного и оптического оборудования. В качестве независимой переменной использован объем инвестиций в отрасль.</p></sec><sec><title>Вывод</title><p>Вывод. Предложен критерий адекватности регрессионных моделей, который представляет собой модификацию используемой в методе наименьших модулей функции потерь.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective. Development of an algorithmic method for estimating the parameters of a linear regression model based on minimizing the sum of excesses of absolute deviations of the calculated values of the dependent variable from the real ones relative to some predetermined level.</p></sec><sec><title>Methods</title><p>Methods. The least absolute values method based on minimizing the city (Manhattan) distance between the vectors of calculated and specified values of the dependent variable is used as a basic method for identifying unknown parameters of the regression equation. Implementation of the method is reduced to a linear programming problem. The problem of minimizing the sum of excesses of absolute deviations of the calculated values of the dependent variable from the real ones relative to some predetermined level is reduced to this problem by introducing some additional constraints and replacing the objective function.</p></sec><sec><title>Result</title><p>Result. Three alternative, highly adequate, versions of a regression single-factor model for the development of the Russian industrial sector engaged in the production of electrical, electronic and optical equipment are constructed. The volume of investments in the industry is used as an independent variable.</p></sec><sec><title>Conclusion</title><p>Conclusion. A criterion for the adequacy of regression models is proposed, which is a modification of the loss function used in the least absolute value method.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>регрессионная модель</kwd><kwd>оценивание параметров</kwd><kwd>метод наименьших модулей</kwd><kwd>линейное программирование</kwd><kwd>уровень ошибок</kwd><kwd>производство электроники</kwd></kwd-group><kwd-group xml:lang="en"><kwd>regression model</kwd><kwd>parameter estimation</kwd><kwd>least absolute values method</kwd><kwd>linear programming</kwd><kwd>error level</kwd><kwd>electronics manufacturing</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">David I.J., Adubisi O.D., Ogbaji O.E., Eghwerido J.T., Umar Z.A.
