我现在碰到一个比较诡异的事情,现在有一个数据集 meanout2,里面的变量delta值有0,0.2,0.4,0.6和0.8.
别的delta的观测都可取出,唯有0.6的说数据集中有0条观测,但是确实不是0观测呀, 怎么回事?
取数据的code:
data meanout3;
set meanout2;
where delta=0.6;
run;
/****log:****/
NOTE: There were 0 observations read from the data set WORK.MEANOUT2.
WHERE delta=0.6;
NOTE: The data set WORK.MEANOUT3 has 0 observations and 6 variables.
NOTE: DATA statement used (Total process time):
