`.data` |
A |

`.S` |
The (K x K) empirical indicator correlation matrix. |

`.csem_model` |
A (possibly incomplete) cSEMModel-list. |

`.conv_criterion` |
Character string. The criterion to use for the convergence check.
One of: " |

`.iter_max` |
Integer. The maximum number of iterations allowed.
If |

`.PLS_ignore_structural_model` |
Logical. Should the structural model be ignored
when calculating the inner weights of the PLS-PM algorithm? Defaults to |

`.PLS_modes` |
Either a named list specifying the mode that should be used for
each construct in the form |

`.PLS_weight_scheme_inner` |
Character string. The inner weighting scheme
used by PLS-PM. One of: " |

`.starting_values` |
A named list of vectors where the
list names are the construct names whose indicator weights the user
wishes to set. The vectors must be named vectors of |

`.tolerance` |
Double. The tolerance criterion for convergence.
Defaults to |

A named list. J stands for the number of constructs and K for the number of indicators.

`$W`

A (J x K) matrix of estimated weights.

`$E`

A (J x J) matrix of inner weights.

`$Modes`

A named vector of modes used for the outer estimation.

`$Conv_status`

The convergence status.

`TRUE`

if the algorithm has converged and`FALSE`

otherwise. If one-step weights are used via`.iter_max = 1`

or a non-iterative procedure was used, the convergence status is set to`NULL`

.`$Iterations`

The number of iterations required.
