ARIMA模型在能源消费总量中的应用 Introduction Thestudyofenergyconsumptionanditspredictionisessentialineconomic,environmental,andpolicyaspects.TheuseofARIMA(AutoregressiveIntegratedMovingAverage)modelsinpredictingenergyconsumptionhasbecomepopularinrecentyears.ARIMAmodelsaremathematicalmodelsthatcanbeusedtoanalyzetimeseriesdataandpredictfuturevalues.ARIMAmodelsarewidelyusedinvariousfields,includingfinance,economics,andengineering.ThispaperaimstoprovideanoverviewoftheuseofARIMAmodelsinpredictingenergyconsumption. OverviewofARIMAModels ARIMAmodelscomprisethreecomponents:theautoregressive(AR)component,theintegrated(I)component,andthemovingaverage(MA)component.Theautoregressivecomponentconsiderstherecentvaluesoftheseries.Theintegratedcomponentadjuststheseriestomakeitstationary,i.e.,withaconstantmeanandvariance.Themovingaveragecomponentconsidersthepasterrorsoftheseries.TheARIMAmodelcombinesthesethreecomponentstodevelopamodelthatcaneffectivelypredictfuturevalues.
