摘要
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。
Many non-linear and non-normal rules are existence in the multifactor and multilevel evaluation of channel pattern while the traditional linear regression analysis cannot fully discover and make use of the potential information.The weight value of relative contribution and variation rules of channel pattern are obtained and the measures of channel regulation are proposed by statistical inference technique called projection pursuit regression.The result shows that the proposed method is effective and reliabl...
