I got the following graph after running the following codes (a fixed-effects model, wg is a dummy variable indicating before or after working group experience).
xtreg hindex c.time2##i.wg i.year, fe cluster(id)
margins i.wg, at(time2 = (0 (10) 10))
marginsplot
As you can see, the two lines intersect My question is, how can I know the exact x value of the intersection point? I know it is something between 3 and 4 based on the x-axis of the plot, but is there any codes to obtain the precise x value? Many thanks!
