The Best Subset Regression for Single Prediction and Its Application

Two calculation schemes,backward algorithm screening prediction and double chest stepwise screening for algorithm of introduction and rejection prediction,were designed and applied using the method of best subset regression for single prediction.The study shows that the method has advantages over other stepwise regression analyses.The method was used to analyze the rainfall data of Xinanjiang River drainage basin during the rainy season (April to September).The results indicate that the method has some predictive ability.
