我按照书里介绍的方法,下载命令ssc install estout,之后提示checking estout consistency and verifying not already installed...all files already exist and are up to date.
但是使用的时候,会出现以下结果:
esttab ols tobit clad,mtitles se star (*0.1 **0.05 ***0.01)
unmatched list of significance symbols and levels
r(198);
是啥原因?求指教!十分困扰,十分感谢!!
