③在DATA语句中使用DROP=或KEEP=选择项,如: DATA B(KEEP X Y) C(KEEP Y); SET A;(7)由数据集A生成含有部分观测的子集B, 一般要借助子集IF语句来实现,如: DATA B; SET A; IF SEX='M'; 最后一句还可写成: IF SEX='M' THEN OUTPUT; 或IF SEX^='M' THEN DELETE; 其目的都是
①DROP=变量名列表 等号后面的所有变量将不出现在此数据集中; ②FIRSTOBS=n 从数据集中第n个观测值开始处理; ③IN=变量名 在SET, MERGE或UPDATA语句里规定一个新变量的名字,其取值指示观测从哪个数据集得到。如: MERGE ONE(IN=A) TWO; 即当前观测取自ONE时, 则A=1,这...

I would be tempted to try the tabulate code (without style overrides as not needed) to create an output data set. Then use that as input to a modified code to display the values but drop the records where that variable is missing. 0 Likes Reply Our biggest data...
