I am using this script to run a multivariate-Cholesky AE model
multAEModel <- mxModel(choleskyACEFit, name="multAE",
mxMatrix( type="Lower", nrow=nv, ncol=nv, free=F, values=0, name="c" ),
This is the error message I get:
Error: The following error occurred while evaluating the subexpression 'solve(sqrt(AE.I * AE.C))' during the evaluation of 'AE.Rc' in model 'univAE' : Lapack routine dgesv: system is exactly singular
I changed starting values without success. I get the same error if I drop only some the c paths.
Sorry to trouble with a silly question...
Thank you, Maria
