冬小麦高产栽培试验数据的投影寻踪回归分析

Projection Pursuit Regression Analysis of Experiment Data on Winter Wheat High Yield Culture

本研究通过对同一批冬小麦高产栽培试验数据的对比分析，阐明了采用传统多元回归方法的弱点和局限性，论述了应用新兴投影寻踪回归方法的显著优势和广阔前景。

Through comparative analysing the same experiment data of winter wheat high yield culture, this study clearly expounds the weakness and limitation of using traditional mutiple regression method, and discusses the obvious superiority and wide applying prospect of using new and developing method - Projection Pursuit Regression (PPR). Thereby it offers much beneficial experience for how to carry out the optimization in agricultural field.
