Wameq, I think you may have a problem using the option -addtable- for the -outreg- command, if you want to use it to combine tables. This option creates a new table in the same document as a previous table, but the tables are completely separate. Otherwise I don't see a problem. Most of your options listed below have nothing to do with marginal effects per se. I can produce a table of marginal effects for multinomial logit as follows: . sysuse auto, clear . mlogit rep78 mpg foreign, nolog baseoutcome(1) If you just use the command . margins, dydx(*) you only get the marginal effects for the first outcome of the -mlogit- model. 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.
