cSEMArguments

An alphabetical list of all arguments used by functions of the cSEM package including their description and defaults. Mainly used for internal purposes (parameter inheritance). To list all arguments and their defaults, use args_default(). To list all arguments and their possible choices, use args_default(.choices = TRUE).

Possible choices for mode are: "modeA", "modeB", "modeBNNLS", "unit", "PCA", a single integer or a vector of fixed weights of the same length as there are indicators for the construct given by "construct_name". If only a single number is provided this is identical to using unit weights, as weights are rescaled such that the related composite has unit variance. Defaults to NULL. If NULL the appropriate mode according to the type of construct used is chosen. Ignored if .approach_weight is not PLS-PM.
