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.

Best regards!
