A vector of composite-construct correlations with element names equal to the names of the J construct names used in the measurement model. Note Q^2 is also called the reliability coefficient. |

The (N x J) matrix of construct scores. |
M is the matrix of the sample counterparts (estimates) of the left-hand side terms in Equation (21) - (24) (Dijkstra and Schermelleh-Engel 2014). The label "M" did not appear in the paper and is only used in the package. Similar is suggested by Wall and Amemiya (2000) using classical factor scores.
