Package: SIRE Type: Package Title: Finding Feedback Effects in SEM and Testing for Their Significance Version: 1.1.0 Authors@R: person("Gianmarco", "Vacca", email = "gianmarco.vacca@unicatt.it", role = c("aut","cre")) Maintainer: Gianmarco Vacca Description: Provides two main functionalities. 1 - Given a system of simultaneous equation, it decomposes the matrix of coefficients weighting the endogenous variables into three submatrices: one includes the subset of coefficients that have a causal nature in the model, two include the subset of coefficients that have a interdependent nature in the model, either at systematic level or induced by the correlation between error terms. 2 - Given a decomposed model, it tests for the significance of the interdependent relationships acting in the system, via Maximum likelihood and Wald test, which can be built starting from the function output.
