В статье рассматривается возможность краткосрочного экономического прогнозирования с помощью моделей авторегрессий комплексных переменных. Приводится классификация возможных модификаций комплекснозначных авторегрессионных моделей. Показываются основные свойства каждого из классов этих моделей. Одна из разновидностей этих комплексно­значных моделей использует текущую и прошлые ошибки аппроксимации, а это значит, что она может быть сравнима с широко распространенной на практике моделью авторегрессии действительных переменных ARIMA(p, d, q). В статье осуществляется такое сравнение как на теоретическом уровне, так и на практическом примере.</p></abstract><trans-abstract xml:lang="en"><p>One of the directions that can expand the instrumental base for modeling the economy is complex-valued economics – ​a section of economic and mathematical modeling devoted to the use of models and methods of the theory of the function of a complex variable in economics. The article discusses the possibility of short-term economic forecasting using autoregressive models of complex variables. A classification of possible modifications of complex-valued autoregressive models is given, and the main properties of each of the classes of these models are shown. One of the varieties of these complex-valued models uses current and past errors of approximation, which means that it can be compared with the widely used model of autoregressive real variables ARIMA(p, d, q). The article makes such a comparison, both on a theoretical level and on a practical example.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>комплекснозначная экономика</kwd><kwd>краткосрочное экономическое прогнозирование</kwd><kwd>авторегрессии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>complex-valued economics</kwd><kwd>short-term economic forecasting</kwd><kwd>autoregressive models</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке РФФИ, грант № 19-010-00610\19 «Теория, методы и методики прогнозирования экономического развития авторегрессионными моделями комплексных переменных».</funding-statement><funding-statement xml:lang="en">This work was supported by the Russian Foundation for Basic Research, Grant No. 19-010-00610\19 “Theory, Methods and Techniques for Forecasting Economic Development by Autoregressive Models of Complex Variables”.</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">Светуньков И.
