针对河型多因素多级判别中存在大量非线性、非正态规律用常规的线性回归判别分析无法充分挖掘和利用其潜在信息,采用投影寻踪回归统计推断技术可获得影响因素的相对贡献权重值及河型变化规律,并提出了河道治理措施。实例检验表明,该方法有效可靠,为河道整治工程提供了理论依据。 In view of the large number of non-linear and non-normal rules in river multi-factor multi-level discrimination, the conventional linear regression discriminant analysis can not fully exploit and exploit the potential information, and the relative contribution weight of influential factors can be obtained by using projection pursuit complex statistical inference technique Value and river patterns, and proposed river management measures. The example test shows that the method is effective and reliable, which provides a theoretical basis for the river regulation project.
