- Abstract
Path Analysis is a statistical method to study the causal relationships between observed variables. The specification and the estimation steps are crucial in the whole process. In fact, the relationships between variables and their status are specified. In addition, the model parameters are estimated based on the so-called correlation matrix implied by the model. Two methods are available to compute this matrix: Jöreskog's method and the Finite Iterative Method. Many researchers recommend that the variances of the endogenous variables to be fixed. For instance, diagonal elements are equal to 1. As a consequence, the present paper aims to show that the two methods are identical. Furthermore, numerical studies and empirical simulations illustrating the advantages of this recommendation are also given.
