SAS学习笔记：SAS过程初步

我错了，还以为是某款统计软件

谢谢，学习了

写的挺好的，我这个小白也能懂

值得借鉴啊

能不能问问

PROCGLM DATA = HW2.data;

      CLASSSEX_Z_ (REF = "0");

      MODELSBP_Y_ = AGE_X_ SEX_Z_/SOLUTION;

RUN;

这里 ref="0" 0代表什么？SOLUTION什么意思？
初学SAS，问题要是太基础不要笑话，要是能给个link更好了，谢谢

支持

PROCGLM DATA = HW2.data;

“REF=’level’ | keyword”
specifies the reference level for PARAM= EFFECT, PARAM= REFERENCE, and their orthogonalizations. For PARAM= GLM, the REF= option specifies a level of the classification variable to be put at the end of the list of levels. This level thus corresponds to the reference level in the usual interpretation of the linear estimates with a singular parameterization.

For an individual variable REF= option (but not for a global REF= option), you can specify the level of the variable to use as the reference level. Specify the formatted value of the variable if a format is assigned. For a global or individual variable REF= option, you can use one of the following keywords. The default is REF=LAST.
************************************************
“SOLUTION”
produces a solution to the normal equations (parameter estimates). PROC GLM displays a solution by default when your model involves no classification variables, so you need this option only if you want to see the solution for models with classification effects.
