RE: st: Plotting stored estimates
I share the view that this is not best approached
as a question depending on stored estimates. In
addition to -graph bar-, note that the sequence
egen meankcons = mean(kcons), by(age_cat)
label var meankcons "fraction consulting with knee pain"
egen tag = tag(age_cat)
lets you follow with any reasonable graph command
as response shown and -if tag- as a way of cutting
down graph size.
