基于时间序列分析的股票价格短期预测与分析姓名：王红芳数学与应用数学一班指导老师：魏友华摘要时间序列分析是经济领域研究的重要工具之一，它描述历史数据随时间变化的规律，并用于预测经济变量值。在股票市场上，时间序列预测法常用于对股票价格趋势进行预测，为投资者和股票市场管理方提供决策依据。本文通过各种预测方法的对比，突出时间序列分析的优势，从时间序列的概念出发介绍了时间序列分析预测法的基础以及其简单的应用模型。文中使用中石化股票的历史收盘价数据，运用时间序列预测法预测出中石化股票的后五个交易日的收盘价，通过对预测价格和实际价格做出对比，表明时间序列预测法的效果比较好。关键词：时间序列；股票价格；预测Theshort-termstockpricepredictionbasedontimeseriesanalysisAbstract:Theanalysisoftimeseriesisoneoftheimportanttoolsforresearchinginthefieldofeconomy,itdescribesthelawofhistoricdatawiththetimepassingbyanditisalsousedtopredictthevalueofeconomicvariables.Inthestockmarket,theforecastingmethodoftimeseriesiscommonlyusedtoforecastthetrendofstockprice,andprovideevidenceofdecisionmakingforinvestorsandmanagements.Inthethesis,throughthecomparisonofvariousforecastingmethodstohighlighttheadvantagesoftheanalysisoftimeseries,beginningwiththeconceptoftimeseries,Iintroducethebasicofforecastingmethodoftheanalysisoftimeseriesaswellasitssimpleapplicationmodel.inthepaper,IusethehistoricclosingpricedataofSinopecsharesandtheforecastingmethodoftimeseriestopredicttheSinopecshares'closingpriceofthelastfivedays,andbycomparisonbetweenpredictingpriceandactualpricetoshowthegoodeffectoftheforecastingmethodoftimeseries.Keywords:Timeseries;Stockprice;Forecast目录第1章前言............................................................................................................11.1研究背景.............................................................................................................11.2预测基础知识.....................................................................................................21.3股票基础知识.....................................................................................................41.4股票预测方法.....................................................................................................4第2章时间序列预测法............................................................................................62.1时间序列预测.....................................................................................................62.1.1时间序列的概念...........................................................................................62.1.2时间序列分析特点.......................................................................................72.1.3时间序列预测法的分类...............................................................................72.1.4时间序列预测法的步骤...............................................................................82.2时间序列预测算法.............................................................................................92.2.1平均数预测法...............................................................................................92.2.2指数平滑法.................................................................................................102.3时间序列模型...................................................................................................132.3.1时间序列模型......................................................................
