In summary, the ARIMA model provides a structured and configurable approach for modeling time series data for purposes like forecasting. Next we will look at fitting ARIMA models in Python. Python Code Example In this tutorial, we will useNetflix Stock Datafrom Kaggle to forecast the Netflix st...

在Python中,可以使用statsmodels库中的`ARIMA`模块来实现ARIMA模型的拟合和预测。 首先,我们需要导入所需的库: import numpy as np import pandas as pd from statsmodels.tsa.arima_model import ARIMA from statsmodels.tsa.stattools import adfuller 接下来,我们可以使用`adfuller`函数来检查数据是否适合进行ARIMA模型...
