In the ACEF model (F is an identified shared environment), is it possible to involve 2 or more identified shared environmental factors (as the mediators) in one model?
In a univariate ACEF model, I want to see to what proportion of a phenotype could be explained by A, C, E, and 3 identified shared environmental factors (e.g., SES, home English use frequency, and school English use frequency). Can I involve all these identified shared environmental factors in one univariate model and see the respective proportion of the phenotype explained by the 3 factors?
Yes, you could add covariates to the model - as part of the covariance matrix or the means vector. Before, you may want to read the following two articles about adding shared environmental covariates: 1 and 2
Many thanks for your reply! Yes, a shared environmental factor could be added in the univariate ACE model as a mediator. However, the current OpenMx scripts seem only support adding one shared environmental factors into the ACE model at one time but not support adding 2 or more factors into the ACE at the same time.
Could you explain further the model you have in mind?
