Construct loading matrix

Usage

gen_loadings(
  CONSTRMAT,
  FIXED = NULL,
  SEED = 123,
  LB = 0,
  UB = 1,
  STDLV = TRUE,
  LLC = NULL
)

Arguments

CONSTRMAT

Binary matrix of dimension \(p*q\). A cell equal to \(1\) indicates that the corresponding element in the loading matrix is free to be estimated. A cell equal to \(0\) fixes the corresponding element in the loading matrix to \(0\).

FIXED

Fixed value to assign to all free loadings. If 'NULL' it draws them randomly from Unif(0,1)

SEED

Random seed.

LB

Lower bound for uniform random generator. Default set to 0.

UB

Upper bound for uniform random generator. Default set to 1.

STDLV

Logical indicator. Set it to TRUE to fix latent variables scale. Set it FALSE to fix loadings scale.

LLC

Linear loadings constraints. Expects a list of constraints. See fit_plFA documentation.
