Oggetto: st: Bivariate density contours
Greetings!
I have share of food expenditure and log of total expenditure variables and
want to plot joint desity of the logarithm of total expenditure and the
share of budget devoted on food in three dimensions. I am wondering if
there's way to plot the curve using stata. Furthermore, I want to plot joint
density surface too. Any help is very useful to me, please let me know.
