Hi all,


When trying to produce a marginal effects graph using fixed effects, the output is blank. However, the graph outputs normally when using random effects.

I'm using the command xtreg in Stata 13


The code I'm using is as follows:

xtreg l3.fed c.index1 i.prom i.member c.index1#i.prom#i.member unemp taylor if tin(2003m1,2007m12), robust fe
qui margins, at ( index1=(-7(2)10) prom=(1) member=(0(1)1) )
marginsplot



Thanks,

Ciaran
