Hello Everyone
I am trying to estimate marginal effects for a conditional logit model that
is essentially identical to the one presented as example 5 on page 227 in
the STATA 9 reference for A-J under the clogit command. In that example,
each person chooses between 3 types of cars: American (excluded category),
Japanese, and European. Their choice depends on their sex and income (both
person specific) and also the number of car dealerships of each type in
their city (person & choice specific). The dataset is available at:
http://www.stata-press.com/data/r9/choice.dta
Does anyone know how to generate a set of marginal effects for each person
specific variable? In other words, after running the clogit model whose
output is given on page 228, I would like to put together a table with the
following information:
Variable Marginal Effect
Female marginal effect for choosing American if female
marginal effect for choosing Japanese if female
marginal effect for choosing European if female
Income marginal effect for choosing American if income inc. by 1 unit
marginal effect for choosing Japanese if income inc. by 1
unit
marginal effect for choosing European if income inc. by 1
unit
Here the marginal effects for female should sum to one and the marginal
effects for income should sum to one.
Any suggestions would be greatly appreciated!
