结构方程模型分析中使用最广泛的计算机程序是Jöreskog和Sörbom的LISREL系列。可以直接进行的约束的唯一类型是将参数固定在常量值和将参数约束为相等。Rindskopf(1983)展示了如何使用这些简单的性质来表示具有更复杂约束的模型，即关于唯一方差的不等约束。在这篇文章中，引入了两个新的概念，这两个概念使得可以做出更广泛的各种约束。“幻影”和“虚构”潜在变量的概念允许对要素负荷和结构模型系数进行相当普遍的相等和不平等约束。
The most widely-used computer programs for structural equation models analysis are the LISREL series of Jöreskog and Sörbom. The only types of constraints which may be made directly are fixing parameters at a constant value and constraining parameters to be equal. Rindskopf (1983) showed how these simple properties could be used to represent models with more complicated constraints, namely inequality constraints on unique variances. In this paper, two new concepts are introduced which enable a much wider variety of constraints to be made. The concepts, “phantom” and “imaginary” latent variables, allow fairly general equality and inequality constraints on factor loadings and structural model coefficients.
