求教：如何在SAS下实现分类决策树CART和支持向量机SVM

shiyiming

大家好！

我初步学习了一些统计分析及数据挖掘，现在在进行一个project，要求对数据整理分析，使用logistic回归，CART：Classification And Regression Tree，SVM：Support Vector Machine 3种方法，并且进行对比。

在此，想请教各位大侠，如何在SAS下做后两种方法，小弟对此完全没有概念……

先谢谢了！

If you don't have license of SAS Enterprise Miner, simply no way. However,you can substitute with R.

to zhangzachary
the book Classification and Regression Tree has source code for CART in C. If you know C, you can translate it into SAS
I am currently working on approximation solution to SVM using existing SAS PROCs, need some time though, too much food in plate

谢谢dapangmao和oloolo~~我还是前期用SAS整理下数据然后导入R用里面的package完成后期模型的对比吧~~
