Hello,
I have a basic question regarding scaling. I read text books and searched online, but could not understand the basic concept of scaling.
Let's say that I have a 2-factor model.
A =~ v1 + v2 + v3
B =~ x1 + x2 + x3
If I constrain a factor variance of A to 1.0, do I have to constrain a factor variance of B to 1.0 as well?
For example, would it be acceptable to constrain a factor variance of A, but constraining one indicator of B?
A =~ NA*v1 + v2 + v3
B =~ x1 + x2 + x3
A ~~ 1*A
I would be very grateful for your help!
