I conducted multi group moderation using critical ratios for differences in AMOS and then I found the group difference by Z-score which was explained by James Gaskin in his youtube channel (https://www.youtube.com/watch?v=ZMYS90AU8bs), but I did not find any research article which has followed this methodology, I request you to provide any research article which has followed this methodology, which would help me a lot in understanding better insights of the methodology.
