Hi everyone,
I am trying to estimate the knot of piecewise latent growth model and using one piece of code from Grimm, Ram & Estabrook's book as my reference (P268-269). However, it reported an error "Error: Illegal label 'L10[1, 1]' detected in matrix 'A'. Square brackets must contain numeric literals when used inside of labels."
Based on a previous discussion https://openmx.ssri.psu.edu//thread/684?q=thread/684 [6], I guess it may result from feature reduction, yet I have no idea how to handle it. Is there any solution to this issue? Any advice or suggestion would be appreciated.
I attached the codes including the simulated data.
--solved, thanks
