Dear Friends
In the last week, at least 3 scholars asked me how to take a categorical variable (with more than two categories) in Multi-Group Analysis (MGA) in Structural Equation Modeling (SEM).
Incidentally, in the last week, I read the paper Multigroup analysis of more than two groups in PLS-SEM: A review, illustration, and recommendations by Cheah Jun Hwa, Suzanne Amaro, and José L. Roldán in Journal of Business Research 156(4):1-19 DOI: 10.1016/j.jbusres.2022.113539 December 2022
So far we can run Multi-group analysis (MGA) with 2 categories in AMOS, SmartPLS, and Adanco. But for a variable with more than two categories, we can use Non-parametric Distance Test (NDT) which is available only in the R-package cSEM.
I've explained this in these 2 videos. The first video on the mandatory requirement of MICOM for the MGA is explained in this video:
