A Graphical Method for Assessing the Identification of Linear Structural Equation Models
Eusebi, Paolo
Structural Equation Modeling: A Multidisciplinary Journal, v15 n3 p403-412 Jul 2008
A graphical method is presented for assessing the state of identifiability of the parameters in a linear structural equation model based on the associated directed graph. We do not restrict attention to recursive models. In the recent literature, methods based on graphical models have been presented as a useful tool for assessing the state of identifiability of the parameters of the model. This article proposes the graphical counterpart of the rank condition of the matrix of structural coefficients, which allows for checking of the identifiability through a simple graphical rule. This approach can be used to develop algorithms. (Contains 4 figures.)
