model.fit()函数返回一个ARIMAResults对象,我们可以在这个对象上调用save()保存到文件模型并且之后可以使用load()来加载它。 frompandasimportSeriesfromstatsmodels.tsa.arima_modelimportARIMAfromstatsmodels.tsa.arima_modelimportARIMAResults# load dataseries = Series.from_csv('daily-total-female-births.csv',...
In this tutorial, you will discover how to make manual predictions with a trained ARIMA model in Python. Specifically, you will learn: How to make manual predictions with an autoregressive model. How to make manual predictions with a moving average model. How to make predictions with an autoreg...

Why reprex? Getting unstuck is hard. Your first step here is usually to create a reprex, or reproducible example. The goal of a reprex is to package your code, and information about your problem so that others can run it…
Choi and Thacker used the ARIMA model (Autoregressive Integrated Moving Average Model) in 1981 to estimate pneumonia and influenza mortality, one of the earliest studies on time series [11]. The percentage of deaths associated with pneumonia and influenza was used as an evaluation index to quantify...
