Calculate factor scores or factor-score coefficients for the latent variables in a structural-equation model.

1 2 3 4 |

`model` |
an object of class |

`data` |
an optional numeric data frame or matrix containing the observed variables
in the model; if present, the estimated factor scores are returned; if absent, the
factor-score |

`center` |
if |

`scale` |
if |

`...` |
arguments to pass down. |

Factor-score coefficients are computed by the “regression” method as
*C^-1 C**, where *C* is the model-implied covariance or
moment matrix among the observed variables and *C** is the matrix
of model-implied covariances or moments between the observed and latent variables.

Either a matrix of estimated factor scores (if the `data`

argument is
supplied) or a matrix of factor-score coefficients (otherwise).
