SAS哪个过程可以完成LAD回归估计

The QUANTREG Procedure does it.

不好意思，我想请问下为什么我的SAS一直提醒我没有quantreg的过程呢？是不是需要安装什么？还是我的SAS9.1版本太低了？

It is an experimental procedure for SAS 9.1. The patch can be downloaded from

If you have SAS/OR you can write the solution yourself. It can be viewed as a linear programming problem.
