请教Treatment Effect Model的问题

*y为因变量，x*是自变量，z为哑元，w*为自变量：

treatreg y x*, tr(z=w*) two

*等价于以下命令：

prob z w*
predict gw, xb
g lambda=normalden(gw)/normal(gw) if z
replace lambda=-normalden(gw)/normal(-gw) if !z
reg y x* z lambda

average treatment effect 平均处理效应 双语例句 1 matching method estimate of the average treatment effect of a job training program 匹配法估计工作培训项目的平均处理效果 2 a structural regression model with measurement errors is proposed to study the impact of measurement errors on estimating the average treatment effect under exchangeable conditions. 提出具有测量误差的结构回归模型，研究可交换条件下测量误差对平均处理效应估计的影响。
