摘要
根据历史资料，应用投影寻踪回归（ＰＰＲ）的基本思想和算法，建立了台风季节台风登陆华南年频次的ＰＰＲ预测模型。结果表明ＰＰＲ模型的预测精度优于逐步回归建模的预测精度。
Based on the historical data,a forecasting model of numbers of landed typhoon in South China is proposed using the original idea and its implement algorithm of projection pursuit regression (PPR) during the yearly season of typhoon.The results show that the forecasting precision of PPR model is much better than that of stepwise regression (SR) model.
