Arguments

THETA

Unconstrained parameter vector.

OPTION

Can take values

`'raw'`	Returns `THETA`.

`'transformed'`	Transformed vector of parameters, with interpretable latent correlations.

`'list'`	List containing the ordered thresholds vector, the loading matrix and the latent correlation matrix.

CONSTRMAT

\(p*q\)-dimensional matrix. Elements set to NA refers to free loading parameters. Elements set to numerical values denote fixed values constraints.

CONSTRLOGSD

\(q\)-dimensional vector. Elements set to NA refers to free latent log standard deviations parameters. Elements set to numerical values denote fixed values constraints.

LLC

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

NTHR

Number of thresholds parameters.

NLOAD

Number of free loadings parameters

NCORR

Number of free latent correlations parameters.

NVAR

Number of free latent variance parameters.
