Webmodel.ARIMA <- Arima (time, order=c (0,0,0)) fitted (model.ARIMA) # or fitted (auto.arima (time)) 进行此操作的原因是 Arima () 返回一个具有原始时间序列和已包含的拟合值的对象。 fitted () 然后简单地返回 model.ARIMA$fitted 。 另一方面, Arima () 在返回的对象中不包含拟合值,因此 fitted () 将必须计算它们。 这很简单,您只需从原始时间序列中减去残差 … Web我正在尝试将此时间序列构建为Arima模型,auto.arima向该时间序列数据建议我Arima (0,0,0)是白噪声,但是在成功创建模型后,当我尝试提取时错误开始模型的拟合值 拟合 …
Web5 mar 2024 · arma(0,0)问题,做了一个arma模型,用来预测,将序列一阶差分后平稳,但通过自相关及偏相关图发现既没有拖尾也没有截尾,即在第一不延迟已经落入2倍标准差之内,且后续延期都没有超出,那是不是意味着可以用arma(0,0)模型来做呢,但是看到要是p和q都等于0的话,是不行的,不知道对不对啊。 Web9 ago 2024 · • 关于简单季节ARIMA原始方程; • 求助,Arima(1,1,1)模型的系数确定; • SAS pro arima过程已经获得系数,但具体表达式是什么呢? • ARIMA(0,1,0)模型; • 问有关AR(P)分析; • 怎么实现ARIMA的乘积形式预测? • ARIMA结果如何写成方程式; • ARIMA的疏系数模型是什么 ...

In that case the best forecast for the next interest rate is the current interest rate. (If you have a non-zero mean, then that also has to be taken into account.)
