Dear lavaan users and experts,
I have a question on the numerical optimization of lavaan.In the file lav_representation_lisrel.R, for computing the objective function, the inverse of I-Beta matrix is required.
Is there any numerical problem due to the singularity of this I-Beta,in computing its inverse?
What can we do to make this inverse operation more stable?
Best,
Yilun
