Dear all, does anybody have experience with the calculation of marginal effects (?effects?) in Mlogit (see Croissant, Package ?mlogit?, p.8)? 1) Is there a good qualitative explanation available for the listed options for the argument ?type? (?aa?, ?)? When do I have to choose aa, ar?? And when can I leave it out? 2) The table in the output ? how is it to read? Does it refer to relative changes (percentage) in the probability or absolute values (percentage points)? Any help including hints for literature is welcome.
