Forecasting the Demand for Telephones in Australia

M. N. Bhattacharyya

Journal of the Royal Statistical Society Series C, 1974, vol. 23, issue 1, 1-10

Abstract: A time series model has been developed for forecasting the demand for telephones in Australia. The model consists of two parts; the first part is a linear regression model involving a non‐stochastic exogenous variable while the second part is a noise structure represented by a Box‐Jenkins moving average model. The model has been fitted to the data by the nonlinear least squares method. The forecast functions and the mean square error of the forecast for lead times 1–36 have been derived.
