Dear Richard et al,
Thanks so much again for your comments. To clarify the matter a bit,
the data is collected from an experimental economics. Each participant
is randomly assigned as player 1, 2, or 3. Then s/he is given a piece
of paper and ased to make the decision. For player 1 It is something
like this:
If Player 2 is in White Group and Player 3 is in Black Group,
I will vote for Plan 12 / Plan 13 / Plan 23. (Please circle one)
If Player 2 is in White Group and Player 3 is in Pink Group,
I will vote for Plan 12 / Plan 13 / Plan 23. (Please Circle one)
and so on.
Your suggestion on the interaction effect is a good one and we can do that.
Our data have information on the participant chracteristics such as
age, education, income etc. We would like to see how these
characteritics may have impact on the decision they make under these
above scenaria. Could you give me a brief idea of how I can run with
MNL model? Is it just like a regular MNL?
Thanks so much and Have A Great Day!

To further clarify - you originally said players are "required" to
vote based on the characteristics of others. But, the above makes it
sound like they are not required to do so. Rather, you want to test
whether the ethnic and economic characteristics of others will affect
the vote? Or, perhaps you could say they are required to vote based
on characteristics, but it is up to them to decide how to do so.
The color coding seems to confound the effects of race and
income. For each of the other 2 players, I'd be inclined to code
their race and income separately. You could then compute
interactions if you thought it might be appropriate or necessary.
I'm still not clear on how to set everything up, but I definitely
don't see how this would be a regression problem. What would the
continuous dependent variable be? Every possible dv presented so far
has 3 categories.
