Web2 set 2024 · ARIMA model, or Autoregressive Integrated Moving Average model, is comprised of 3 models as follows: AR (p): Autoregression model, which is based on the relationship between the current observation and observations in previous time lags. The p parameter here denotes the number of lags to be included in the model. WebAn ARIMA, or autoregressive integrated moving average, is a generalization of an autoregressive moving average (ARMA) and is fitted to time-series data in an effort to forecast future points. ARIMA models can be especially efficacious in cases where data shows evidence of non-stationarity.
