随机观测值生成我用了两种,一种是迭代随机生成,一种是用arima.sim函数生成一列符合arima(p,q)模型的数据。install.packages("tseries") #安装"tseries"包,仅需在首次运行时安装 install.packages("forecast") #安装"forecast"包,仅需在首次运行时安装
In this case, it can be beneficial to train a single model jointly over all of the time series. DeepAR+ takes this approach. When your dataset contains hundreds of feature time series, the DeepAR+ algorithm outperforms the standard ARIMA and ETS methods. You can also use the trained model...

In Ref. [33], univariate and multivariate wind speed forecasting is done for different heights at the same location and found to obtain better performance than ARIMA models. Ref. [34] explains another work in which RNN is used to obtain three day-ahead prediction of wind energy in the ...
Auto-ARIMA model was able to predict the stock price forecast boundaries including the actual stock price in the test set. VAR model was not able to accurately predict the price of the equity nor the trend. LSTM model seems to have predicted the trend of the equity price, but not an ...
. The new function checkresiduals makes this very easy: it produces a time plot, an ACF, a histogram with super-imposed normal curve, and does a Ljung-Box test on the residuals with appropriate number of lags and degrees of freedom. fit <- auto.arima(WWWusage) checkresiduals(fit) ## ...
