Description Usage Arguments Details Value See Also Examples

View source: R/specify_constructs.R

Description

composite creates the composite measurement model matrix for a specific construct, specifying the relevant items of the construct and assigning the relationship of either correlation weights (Mode A) or regression weights (Mode B).

Usage

1

Arguments

construct_name

of construct

item_names

returned by the multi_items or single_item functions

weights

is the relationship between the construct and its items. This can be specified as correlation_weights or mode_A for correlation weights (Mode A) or as regression_weights or mode_B for regression weights (Mode B). Default is correlation weights.

Details

This function conveniently maps composite defined measurement items to a construct and is estimated using PLS.

Value

A vector of the indicators for a composite.
