You can use the -twoway kdensity- command to graph more than one
kdensity in the same graph. Although the help file for -twoway
kdensity- doesn't show a -weight- option, weights can indeed be
used with the command (the help file will be changed in a future
update). Since you want more than one kdensity in the same
graph, you'll need to overlay two -twoway kdensity- graphs along
with a weight for each. For example:
. tw kdensity var1 [w=weight1] || kdensity var2 [w=weight2]
You can find further information on -twoway kdensity- in [G]
-graph twoway kdensity-.
