请问楼主,我的一直是这样的:
. permute did beta = _b[did] se = _se[did] df = e(df_r), ///
> reps(500) rseed(123) saving("simulations.dta"): ///
> reghdfe y did, absorb(country year) vce(robust)
program did not found
安装它这个命令也不行:
. ssc install permute
ssc install: "permute" not found at SSC, type search permute
(To find all packages at SSC that start with p, type ssc describe p)
r(601);
我是stata17,去看了ado\base\p里面也是有permute(...)的东西的。一直解决不了这个问题
