I am familiar with the hessian matrix having the square in the numerator and a product of partial derivatives in the denominator.
However, I have come across a different expression (see attached), source: https://users.ugent.be/~yrosseel/lavaan/lavaan2.pdf (slide 43)
A - represents a hessian matrix.
I am curious are the one attached and usual hessian matrix interchangeable somehow? Why is there no square and a derivative appears in the denominator in the attached example?
