What about (you can add more graphs to this plot using the
-addplot()- option):
*----------------- begin example -----------------
clear
set obs 100
set seed 1234
gen id = _n
gen e = uniform()
expand 5
gen x = uniform()
gen y = -.6 + 1.4*x^.5 + .5*(x>.5) + e
fracpoly reg y x, cluster(id)
fracplot
*------------------ end example ------------------
Hope this helps,
Maarten
