I am running multiple structural models and appear to have the same issue with all the models. In each of the outputs the certain paths appear to be fixed to 1.0 and another value.
For instance in the structural model, EU -> BI -> U (files EUBIU.dat & EUBIU.R), the paths from EU -> BI = 1 and the path from BI -> U = 1.
Another model (files PUEUBI.data & PUEUBI.R), the paths EU -> PU = 1.0, while the paths from EU -> BI and PU -> BI are both equal to 1.0.
I think I may be constraining these paths to be either equal to 1.0 or equal to each other.
I have attached the syntax and data sets I used for your convenience . The syntax is modified from Cheung (2013) metaSEM: An R Package for Meta-Analysis using Structural Equation Modeling. Any assistance is greatly appreciated.
