ARIMA Model in R: Complete Guide

In R language, you can fit an ARIMA model using the arima() function, the specific steps are as follows:

1. : prediction
2. use the arima() function

install.packages("forecast")
library(forecast)

1. Prepare time series data assuming the data is ts_data, which is a time series object.
2. Use the arima() function to fit an ARIMA model by specifying the order parameter to determine the orders of the ARIMA model. For example, to fit an ARIMA(1,1,1) model, you can use the following code:

model <- arima(ts_data, order=c(1,1,1))

1. Can you give me a summary of it?

summary(model)

1. predict()

forecast(model, h=10) # 预测未来10个时间点的值

This allows fitting the ARIMA model in R language and making predictions.
