TWO CURVE MODELS FOR FITTING AND FORECASTING SUSTAINABLE GROWTH AND RELATED ALGORITHMS FOR ESTIMATING THE PARAMETERS |
| |
| Abstract: | In this paper, two curve models are proposed to fit and forecast sustainable growth. Their propeties are also discussed and the related nolinear programming algorithms are developed for estimating the parameters. The two models are verified in fitting and forecasting the average per unit yield rice output in Fujian and the total food output in China as well. |
