R语言集成模型：提升树boosting、随机森林、约束最小二乘法加权平均模型融合分析时间序列数据

特别是在经济学/计量经济学中，建模者不相信他们的模型能反映现实。比如：收益率曲线并不遵循三因素的Nelson-Siegel模型，股票与其相关因素之间的关系并不是线性的，波动率也不遵循Garch(1,1)过程，或者Garch(?,?)。我们只是试图为我们看到的现象找到一个合适的描述。模型的发展往往不...

R语言ARIMA集成模型预测时间序列分析

本文我们使用4个时间序列模型对每周的温度序列建模。第一个是通过auto.arima获得的，然后两个是SARIMA模型，最后一个是Buys-Ballot方法。我们使用以下数据 k=620 n=nrow(elec) futu=(k+1):n y=electricite$L...
