An ARIMA(0, 1, 1) model without constant is a basic exponential smoothing model. [ 9 ] An ARIMA(0, 2, 2) model is given by X t = 2 X t − 1 − X t − 2 + ( α + β − 2 ) ε t − 1 + ( 1 − α ) ε t − 2 + ε t {\displaystyle X_{t}=2X_{t-1}-X_{t-2}+(\alpha +\beta -2)\varepsilon _{t-1}+(1-\alpha )\varepsilon _{t-2}+\varepsilon _{t ...
ARIMA univariate and multivariate models can be used in forecasting a company's future cash flows, with its equations and calculations based on the past values of certain factors contributing to cash flows. Using time-series analysis, the values of these factors can be analyzed and extrapolated to predict the future cash flows for a company.
