Summary

A non-linear AR(1) process is investigated when the associated white noise has a rectangular distribution. The process is a modification of the logistic model and an important feature is that it is possible to derive explicit formulae for extrapolation. Some properties of the extrapolation are derived and it is proved that the least squares extrapolationm steps ahead converges to a constant asm→∞. The least squares extrapolation is compared with the naïve extrapolation and the differences between them are shown to be small in some examples.
