在SAS中,在PROC LOGISTIC中指定参考级别是指在进行逻辑回归分析时,可以通过指定一个分类变量的参考级别来比较其他级别与该参考级别之间的差异。 逻辑回归是一种广泛应用于分类问题的统计分析方法,常用于预测二元或多元分类结果。在SAS中,PROC LOGISTIC是用于执行逻辑回归分析的过程。 在PROC LOGISTIC中,可以使用CLASS语句...
PROC LOGISTIC的CLASS statement默认的option是PARM=EFFECT,这一点与PROC PHREG不同(default为PARM=REF)。 PARM=REF:各水平与第一个level进行比较。 PARM=EFFECT:将每个水平都看作独立的参数进行估计和解释,没有明确的基准水平;各水平与所有水平的平均效果进行比较。 解决方案:在CLASS中指定option为PARM=REF ...
