Web21 ago 2024 · Autoregressive Integrated Moving Average, or ARIMA, is a forecasting method for univariate time series data. As its name suggests, it supports both an autoregressive and moving average elements. The integrated element refers to differencing allowing the method to support time series data with a trend. WebAn ARIMA (0, 0, 0) model is a white noise model. An ARIMA (0, 1, 2) model is a Damped Holt's model. An ARIMA (0, 1, 1) model without constant is a basic exponential smoothing model. [9] An ARIMA (0, 2, 2) model is given by — which is equivalent to Holt's linear method with additive errors, or double exponential smoothing. [9]
