title: Forecasting with growth curves:  the effect of error structure.
abstract: "The main theme of this paper is an investigation into the importance of error structure as a determinant of the forecasting accuracy of the logistic model.  The relationship between the variance of the disturbance term and forecasting accuracy is examined empirically.  A general local logistic model is developed as a vehicle to be used in this investigation. Some brief comments are made on the assumptions about error structure, implicit or explicit, in the literature."  The results suggest that "the variance of the disturbance term, when using the logistic to forecast human populations, is proportional to at least the square of population size."
