calculateWeightsKettenring

Calculate composite weights using GCCA

Description

Calculates composite weights according to one of the the five criteria "SUMCORR", "MAXVAR", "SSQCORR", "MINVAR", and "GENVAR" suggested by Kettenring (1971).

Usage

calculateWeightsKettenring(
  .S              = args_default()$.S, 
  .csem_model     = args_default()$.csem_model,   
  .approach_gcca  = args_default()$.approach_gcca
  )

Arguments

`.S`	The (K x K) empirical indicator correlation matrix.
`.csem_model`	A (possibly incomplete) cSEMModel-list.
`.approach_gcca`	Character string. The Kettenring approach to use for GCCA. One of "SUMCORR", "MAXVAR", "SSQCORR", "MINVAR" or "GENVAR". Defaults to "SUMCORR".

Value

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: NULL
$Modes: The GCCA mode used for the estimation.
$Conv_status: The convergence status. TRUE if the algorithm has converged and FALSE otherwise. For .approach_gcca = "MINVAR" or .approach_gcca = "MAXVAR" the convergence status is NULL since both are closed-form estimators.
$Iterations: The number of iterations required. 0 for .approach_gcca = "MINVAR" or .approach_gcca = "MAXVAR"
