To get a full table of marginal effects, you have to calculate them for each outcome, and use the -merge- option in -outreg- to combine them: > > . margins, dydx(*) predict(outcome(2)) > . outreg, marginal ctitle("",2) > . margins, dydx(*) predict(outcome(3)) > . outreg, marginal merge ctitle("",3) > . margins, dydx(*) predict(outcome(4)) > . outreg, marginal merge ctitle("",4) > . margins, dydx(*) predict(outcome(5)) > . outreg, marginal merge ctitle("",5) > > This produces the following table: > > -------------------------------------------- > 2 3 4 5 > -------------------------------------------- > mpg -0.002 -0.010 -0.003 0.014 > (0.23) (0.92) (0.34) (2.40)* > foreign -1.334 0.859 0.577 0.245 > (0.01) (0.01) (0.02) (0.04) > N 69 69 69 69 > -------------------------------------------- > * p<0.05; ** p<0.01 > > You can put the same code into a loop: > > . outreg, clear > . forvalues o = 2/5 { > qui margins, dydx(*) predict(outcome(`o')) > outreg, marginal merge ctitle("",`o') nodisplay > } > . outreg, replay > > If you still find that -outreg- is not lining up columns as it should, please create an example using Stata's auto.dta dataset so that I can reproduce your code. > > John > > > On Sep 8, 2012, at 4:05 PM, Wameq Raza <wameq.r@gmail.com> wrote: > >> Hello STATA Users, >> I just started working with outreg recently and have had no trouble >> getting tables for my binomial models. >> But when I tried to get margins tables for a MNL model, the marginal >> effects and the standard errors come >> up all over the place.
