Extracts the matrices with indices of model parameters from a latent variable model (lvm). Returns a list with

  • A: Matrix with fixed parameters and ones where parameters are free

  • J: Manifest variable selection matrix

  • M0: Index of free regression parameters

  • M1: Index of free and unique regression parameters

  • P: Matrix with fixed variance parameters and ones where parameters are free

  • P0: Index of free variance parameters

  • P1: Index of free and unique regression parameters

  • npar.var: Number of covariance parameters
