Hi Statalisters,
Is it possible to save margins estimates as a new variable? In the example below, I would like to create a variable that contains the marginal effects of ycn across the whole range of age in order to then use this variable in a two-way graph (that way I will be able to combine several "margins plots" in one graph). You can of course create this variable manually, but that is so tiresome...

I found a similar post (https://www.statalist.org/forums/for...=1566557316931) but I do not manage to get the code provided in that post to work in my case.


Code:
.  . use http://www.stata-press.com/data/r13/margex, clear
(Artificial data for margins)

. . reg outcome c.ycn c.age c.age#c.ycn

      Source |       SS       df       MS              Number of obs =    3000
-------------+------------------------------           F(  3,  2996) =  182.34
       Model |  65.2517193     3  21.7505731           Prob > F      =  0.0000

. margins, dydx (ycn) at (age=(20(1)60))
Thanks in advance!

Kind regards,
