Lulu, would a contour plot be helpful in your case? twoway contour share odo bill Best, Sergiy Radyakin On Wed, Oct 30, 2013 at 9:00 AM, Joe Canner <jcanner1@jhmi.edu> wrote: > Lulu, > > Based on the example in the Train paper, it appears that you want a three-dimensional plot, not a two-dimensional plot.

The closest thing is -surface- from SSC which does wireframe surface plots. You can use the -nowire- option to plot each point separately with a dropline instead of connecting them with a wire frame. > > . surface odo bill share, nowire > > You might also want to check out Stata's -graph twoway contour- which is designed for plotting three variables in two dimensions. > > Regards, > Joe Canner > Johns Hopkins University School of Medicine > > -----Original Message----- > From: owner-statalist@hsphsun2.harvard.edu [mailto:owner-statalist@hsphsun2.harvard.edu] On Behalf Of Lulu Zeng > Sent: Wednesday, October 30, 2013 7:07 AM > To: statalist@hsphsun2.harvard.edu > Subject: st: 2 dimensional graph for joint distribution > > Dear Statalist > > I am having trouble creating a two dimensional joint distribution bar graph in Stata. > > I'm trying to graph the joint distribution of 2 coefficients I estimated from a nonparametric choice model using fixed mass point method following Kenneth Train's approach in his 2008 paper (EM Algorithms for nonparametric estimation of mixing distributions).
