发帖数: 365 | 1 请教一个sas问题哈，
我想比较黑人和白人（race）的平均年龄（age）的差别,t test。但是我是survey的数
据。试了半天surveymeans，但是总是说我的by race那句话有问题，跟total＝有冲突。
PROC SURVEYMEANS DATA=ONE TOTAL=AAA(RENAME=(NSTRATUMCEN=_TOTAL_));
STRATA XXX;
WEIGHT XXX;
VAR AGE;
BY CRACE;
RUN;
ERROR: Not all BY variables from the ONE data set are present in the AAA
data
set, or some BY variables have different attributes in the two data
sets
咋办？咋办？咋办？
感谢！感谢！感谢！ |
