本文探讨了各种治疗参数之间的关系在一个潜在的变量模型时，治疗的效果取决于收件人的观察和未观察到的特点。我们展示了这种关系如何可以用来确定治疗参数时，他们被确定和绑定的参数时，他们没有被确定。
This paper examines the relationship between various treatment parameters within a latent variable model when the effects of treatment depend on the recipient's observed and unobserved characteristics. We show how this relationship can be used to identify the treatment parameters when they are identified and to bound the parameters when they are not identified.
