WebDec 16, 2024 · When implementing an ARIMA model, it is particularly common to automate the selection of the p, d, q coordinates using a library such as auto.arima in R and pmdarima in Python. Background. For context, p is the autoregressive term which indicates the extent to which the model relies on past values to predict future ones. WebMay 24, 2024 · Auto-Regressive Integrated Moving Average (ARIMA) is a time series model that identifies hidden patterns in time series values and makes predictions. For example, an ARIMA model can predict future stock prices after analyzing previous stock prices. Also, an ARIMA model assumes that the time series data is stationary.
