请问各位大佬,bootstrap检验结果怎么看呢?得出下面的结果,能说明存在有调节的中介吗?判断标准是什么呢?
以下是我的代码
generate Regulation_FinIndex=Regulation*FinIndex
capture program drop Fun_Med
program Fun_Med, rclass
sem(FinCons <- FinIndex Regulation Regulation_FinIndex $X_CON Industry Year) (Innovation<- FinCons FinIndex Regulation Regulation_FinIndex $X_CON Industry Year) , nocaps
return scalar cielw = (_b[FinCons:FinIndex]+($FinCons-$s)*_b[FinCons:Regulation_FinIndex])*_b[Innovation:FinCons]
return scalar ciemn =(_b[FinCons:FinIndex]+($FinCons)*_b[FinCons:Regulation_FinIndex])*_b[Innovation:FinCons]
return scalar ciehi = (_b[FinCons:FinIndex]+($FinCons+$s)*_b[FinCons:Regulation_FinIndex])*_b[Innovation:FinCons]
end
set seed 12345
*运行命令
Fun_Med
*bootstrap中介效应
bootstrap r(cielw) r(ciemn) r(ciehi), reps(1000) nodots:Fun_Med
estat boot, bc percentile
下面是stata的bootstrap运行结果
*bootstrap中介效应
. bootstrap r(cielw) r(ciemn) r(ciehi), reps(1000) nodots:Fun_Med
