I get the following error messeage from openMX:
Error in mxModel("ACE", mxMatrix(type = "Iden", nrow = 4, ncol = 4, name = "I"), :
argument is missing, with no default
this "ACE" mxModel object contains only mxMatrix and MxAlgebra ellements.
It is one of six submodels in a bigger model this bigger model contains an mx Algebraobjective the other 5 submodels contain data and a mxFIMLObjective each for the different groups.
Which argument am i missing in this ACE mxModel? which are the required model arguments anyway?
