Forecasting with nonlinear time series model: A Monte-Carlo bootstrap approach

Autor: Nosakhare Ekhosuehi, S. E. Omosigho

Publikováno v: Journal of Science and Technology (Ghana); Vol 35, No 3 (2015); 52-59

In this paper, we propose a new method of forecasting with nonlinear time series model using Monte-Carlo Bootstrap method. This new method gives better result in terms of forecast root mean squared error (RMSE) when compared with the traditional Boot
