摘要
本文将逐步回归和曲线拟合结合起来,设计了一种逐步回归曲线拟合模型,实例分析表明,该模型与逐步回归相比,其拟合误差和预报误差均较小,具有较高的使用价值。
The stepwise regression and curve fitting have been linked in this paper. A combination new model-stepwise regression curve fitting model has been designed. It is found that both the fitting error and the forecasting error of the new model are smaller compared with the stepwise regression method,so it is valuable in meteorological factors forecasting.
