Dalhia,
Thanks for the correction.
I may not understand the relation between the variable group, which
took the values 1 and 2 in your initial example, and group_dummy in
the interaction model. I assume that group_dummy is 0 when group = 1
and 1 when group = 2.
I'm also assuming that group_dummy is different from x2.
