重新输入ssc install reghdfe、ssc install ftools、ssc install ivreg2这三个命令,看stata弹出来的红色文 ...
你好,请教一下,按你说的执行了这三个命令后回归,还是报错r(198),请问有什么解决办法吗?如下所示:
. ssc install reghdfe
checking reghdfe consistency and verifying not already installed...
all files already exist and are up to date.
. ssc install ftools
checking ftools consistency and verifying not already installed...
installing into c:\ado\plus\...
installation complete.
. ssc install ivreg2
checking ivreg2 consistency and verifying not already installed...
all files already exist and are up to date.
.
end of do-file
. reghdfe y x i.year,absorb(Stkcd) cluster(Stkcd)
invalid syntax
(error occurred while loading reghdfe.ado)
r(198);
