Prof James Gaskin response to my question:

Hi Rodney,

You can definitely do a multigroup with more than two groups. However, the human mind isn’t very good at comparing more than two things at once. For this reason, our tools only do two at a time. So, you could do group A vs B, then B vs C, then A vs C, or you could do A vs BC, B vs AC, and C vs AB. To do this in AMOS, you can just create three groups (in the same place I show creating two groups), and then when you are assigning data to the groups, just make sure you assign data to all three groups based on the grouping variable and value, and then you can toggle between those three groups in the output (on the bottom left of the output window).

Well, I think there is no problem in it. You can either develop a composite variable for these or you can do step by step modeling for checking this thing. 

Best wishes and happy researching. 

Dear Mr Aziz

Thank you so much for your response.

Regards, Rodney

Dear Rodney Duffett

Still i confused for multi-group analysis using Amos for more than 2 groups,

I would be most grateful if you could send me a link of tutorial videos for compression more two groups or any published paper in this matter. 

Best regards,
