rho_A: seminr rho_A Function

In seminr: Building and Estimating Structural Equation Models

seminr rho_A Function

Description

The rho_A function calculates the rho_A reliability indices for each construct. For formative constructs, the index is set to 1.

Usage

rho_A(seminr_model, constructs)

Arguments

seminr_model	A seminr_model containing the estimated seminr model.
constructs	A vector containing the names of the constructs to calculate rhoA for.

Value

A matrix containing the rhoA metric for each construct.
