您好!我的问题中,核心解释变量是一个0-1虚拟变量,在运行代码时,一直是
There exist time-invariant individual(s) (maybe only one obs): y1 ......
xtdev2(): 3301 subscript invalid
thestm2(): - function returned error
<istmt>: - function returned error
后面,我把这个0-1变量先去掉,结果就是跳出红色的There exist time-invariant individual(s) (maybe only one obs): y1......
但是能运行出结果。
