Web21 Apr 2024 · SARIMA (Seasonal ARIMA) is a classical, statistical forecasting method that predicts the forecast values based on past values, i.e lagged values (AR) and lagged errors (MA). Unlike Holt-Winter's (or ETS), it needs the time series to be stationary before it can be used. That's where the "Integrated" part comes from. Web• Forecasted cash demand on daily, weekly and monthly basis for ATM refilling using R code • Compared forecast results of various time series models like Simple Exponential, Double Exponential Smoothing, Holt-Winters, ARIMA and for accuracy residuals were analyzed using MAPE and ACF plot .
