We should be able to fix this by allowing "restrict" and "estimate" to operate on the (anonymous) "last model" in the case where the last model is a system. That is, I'll aim to make the following variant on Ofer's function work: function ... system method=fiml # system spec end system restrict # restriction spec end restrict estimate method=fiml end function Allin Cottrell
