Reza,
What you see are the *generalized* Lorenz curves. Use to option -lorenz-
to get Lorenz curves:
glcurve income,gl(g1) p(p1) nograph lorenz
glcurve inc2,gl(g2) p(p2) nograph lorenz
glcurve inc3,gl(g3) p(p3) nograph lorenz
> My question is: (1) How do I change this to plot the three measures
simulataneously?
>(2) How do I include the 45 degree line on the graph?
Use -twoway function- to get the 45 degree line
twoway (line g1 p1, sort) (line g2 p2, sort) (line g3 p3, sort)
(function y=x ,range(0 1))
Hope this helps,
Philippe
