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. WebAug 30, 2024 · ARIMA is a very popular statistical method for time series forecasting. ARIMA stands for Auto-Regressive Integrated Moving Averages. ARIMA models work on the following assumptions –. The data series is stationary, which means that the mean and variance should not vary with time.
