rho_A

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)

Arguments

seminr_model

A seminr_model containing the estimated seminr model.

Value

A matrix containing the rhoA metric for each construct.
