摘要
Abstract
Three new methods for selection of the predictors are advanced as nonlinear stepwise regression,nonlinear stepwise regression with principal component and nonlinear stepwise regression with rotated principal component.The test results show that the forecasting model constructed with the predictors selected by nonlinear stepwise regression with principal component has the highest skill score of forecast for Brown Planthopper(BPH).The forecasting accuracy is 80 percent.关键词
