本来是要打开这个数据的。
结果stata出这样的结果。
怎么办呢?
大牛们有没有遇到过这种情况啊。
样本跟变量都不能删掉啊。
no room to add more observations
An attempt was made to increase the number of observations beyond what is currently possible. You have the
following alternatives:
1. Store your variables more efficiently; see help compress. (Think of Stata's data area as the area of a
rectangle; Stata can trade off width and length.)
2. Drop some variables or observations; see help drop.
3. Increase the amount of memory allocated to the data area using the set memory command; see help memory.
