求问各位大神，Amos中，该如何把两个系数定为相同？不是把两个都设为同一个数，应该是让他们等同起来，constrain the two parameters to be equal。
具体描述一下，“If we constrain the adolescent’s actor effect and the mother partner effect to be equal, we gain a degree
of freedom and the chi-square will be non-zero. If the chi-square were statistically significant, we would reject the null hypothesis that the two covariances are equal.”
新模型和原模型自由度的差值是1。
谢谢，求助啊求助~~
