發(fā)布時(shí)間:2018-11-24 07:33
【摘要】:針對多元馬爾可夫鏈模型分析中,待估參數(shù)數(shù)量大而導(dǎo)致估計(jì)困難的問題,文章提出了改進(jìn)方法。以一元預(yù)測誤差最小為優(yōu)化目標(biāo),對列間權(quán)重參數(shù)進(jìn)行了分批次優(yōu)化求解。應(yīng)用多元馬爾可夫鏈模型,對股票五大行業(yè)分類指數(shù)序列進(jìn)行建模,研究了各行業(yè)分類指數(shù)相互間的內(nèi)在相依特征。應(yīng)用數(shù)據(jù)序列間的多元交互信息,對行業(yè)分類股指序列進(jìn)行了預(yù)測。
[Abstract]:In order to solve the problem of large number of parameters to be estimated in multivariate Markov chain model analysis, an improved method is proposed in this paper. With the minimum prediction error as the optimization objective, the weight parameters between columns are solved by batch optimization. In this paper, the multiple Markov chain model is used to model the stock classification index series of five major industries, and the internal dependence characteristics of each industry classification index are studied. This paper predicts the industry classification stock index series by using the multiple interactive information between the data series.
