В первой части статьи проанализированы данные репрезентативной выборки Российского мониторинга экономического положения и здоровья населения (РМЭЗ, RLMS) по индивидам в 2008-2017 гг, построены квантили 10%-95% по заработной плате с учетом годовой инфляции и проанализированы их колебания и изменения за 10 лет. Во второй части статьи приведен временной ряд индекса реальной заработной платы из набора динамических рядов макроэкономической статистики РФ в 2000-2018 гг Выполнено моделирование временного ряда с помощью математических моделей ARIMA (p, d, q): построен стационарный временной ряд по данным индекса заработной платы. Результаты прогноза модели, найденной автоматически среди моделей ARIMA (p, d, q) с показателями d≤5, p≤5, сопоставлены с прогнозами моделей, полученных при p = 6 или q = 6 по двум метрикам. Указано значение информационного критерия Акаике (AIC) для построенных моделей. Предложены модели с p = 6 и q = 6, которые дают прогноз лучший, чем автоматически подобранная модель с показателями d≤5, p≤5. Это связано с сезонными факторами, присущими индексу заработной платы, из-за которых при прогнозировании следует учитывать данные 6-ти- и 12-ти-месячной давности. Показано, что индекс заработной платы достигает пика приблизительно раз в 6 месяцев, что связано с отпускными выплатами, приходящимися, в основном, на конец года и на летние месяцы. Дальнейшие исследования могут быть направлены на более совершенную по качеству декомпозицию временного ряда на тренд, сезонную составляющую и шум, а также на сравнение методик вычислений коэффициентов моделей ARIMA в разных статистических пакетах.</p></abstract><trans-abstract xml:lang="en"><p>In the paper changes of the Russian citizens’ welfare are explored. The time lapse of the data is: 2000-2018. In the first part of the paper the representative individual samples of “The Russian Longitudinal Monitoring Survey - Higher School of Economics (RLMS-HSE)” data of the 2008-2017 time period are analyzed. The 10%-95% quantiles of the salary have been constructed with the regard to year inflation, and their behavior has been analyzed. In the second part the monthly wage index based on the dynamic series of macroeconomic statistics of the Russian Federation data (2000-2018) has been explored. The mathematical models of the wage of this time lapse have been presented. They are based on the ARIMA (p, d, q) models with d≤5, p≤5. Forecasts of these models have been compared to predictions of the models with parameters p = 6 or q = 6. The constructed models have made better forecast than the automatically fitted ARIMA model with d≤5, p≤5. They have been compared using two metrics, and also the Akaike information criterion (AIC) has been considered. The seasonal factors of the wage index have been taken into account. It has been shown that the lags of 6 and 12 months are connected to the today wage index; there are maxima of this value situated at the end of the year or in summer. It’s explained with the vacations which traditionally take place in summer, and also officially held vacations in January. The further research is going to target the trend - seasonal - noise decomposition of time series. Statistical packages which are often in use have got different methods to compute the ARIMA coefficients. That fact is also going to be under research.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Российский мониторинг экономического положения населения</kwd><kwd>РМЭЗ</kwd><kwd>RLMS</kwd><kwd>квантили</kwd><kwd>индекс реальной заработной платы</kwd><kwd>ARIMA</kwd><kwd>стационарность</kwd><kwd>временные ряды</kwd><kwd>прогнозирование</kwd><kwd>информационный критерий Акаике</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Russian Longitudinal Monitoring Survey</kwd><kwd>RLMS</kwd><kwd>quantiles</kwd><kwd>real salary index</kwd><kwd>ARIMA</kwd><kwd>stationarity</kwd><kwd>time series</kwd><kwd>prediction</kwd><kwd>forecast</kwd><kwd>Akaike informational criterion</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">«Российский мониторинг экономического положения и здоровья населения НИУ-ВШЭ (RLMS-HSE)», проводимый Национальным исследовательским университетом «Высшая школа экономики» и ООО «Демоскоп» при участии Центра народонаселения Университета Северной Каролины в Чапел Хилле и Института социологии Федерального научно-исследовательского социологического центра РАН. http://www.cpc.unc.edu/projects/rlms , http://www.hse.ru/rlms.</mixed-citation><mixed-citation xml:lang="en">«The Russian Longitudinal Monitoring Survey - Higher School of Economics (RLMS-HSE)», conducted by the National Research University Higher School of Economics and ООО “Demoscope” together with Carolina Population Center, University of North Carolina at Chapel Hill and the Federal Center of Theoretical and Applied Sociology of the Russian Academy of Sciences. http://www.cpc.unc.edu/projects/rlms , http://www.hse.ru/rlms.
