Subject: Re: st: After mlogit: Graphing predicted probabilities for
transition between 2 subgroups
Hi Marten, dear list,
thanks for the helpful suggestion. My only problem is that I do not want
to compare the overall probability for entering the other group.
What I need is the additional effect for a factor change in education,
if teamsize is low/medium/high.
Any suggestions? Thanks in advance, Stefan
