WebbARIMA models are a subset of linear regression models that attempt to use the past observations of the target variable to forecast its future values. A key aspect of ARIMA models is that in their basic form, they do not consider exogenous variables. WebbArima from R’s forecast package allows us to create a model of this type with relative ease. What amount of data does an ARIMA model require? The rule of thumb for autoregressive integrated moving average (ARIMA) models is to have at least 50 observations, but preferably more than 100 (Box and Tiao 1975).
