This page illustrates the use of graph3d.ado for Stata. See Stata. To download the graph3d package including the ado file type
-
. ssc install graph3d
in Stata or click
Before running any of the examples, set up the exemplary dataset by running
-
. clear
. set obs 630
. gen x = int((_n - mod(_n-1,30) -1 ) /30 )
. gen z = mod(_n-1,30)
. gen y = normalden(x,10,3)*normalden(z,15,5)*10000
. gen w = x*z
What Stata experts say:
