请问，在SAS中做ordinal logistic regression（有序逻辑回归）需要安装特别的模块吗？
还有点击“solutions”下面的“Analysis”下的“Analyst”，出现如下一段话：
ERROR: The SAS/STAT product with which the procedure is associated is either not licensed for your system or the product license has expired. Please contact your SAS installation representative.
ERROR: Cannot open SASHELP.APPVIEW.PRIMARY.SCL.
我正在学用SAS，V8的，安装的时候就安装了SAS system，是不是装少东西了？
