mean of tenure
graph dot tenure, over(occ7) over(collgrad)
over(married)
We can add a third
over()
option, in
this case further breaking the
tenure
down by whether one is married. Note
that the first
over()
variable (
occ7
)is
now treated as multiple

When you use three
over()
options,
the first variable is then treated as

specified the

option. This
