twoway (lfitci ownhome pcturban80,
bcolor(stone)
)
(scatter ownhome pcturban80)
We use the
bcolor(stone)
option to
change the color of the area and outline
of the confidence interval. You can use
the options illustrated with
twoway
rarea
to control the display of the area
encompassing the confidence interval,
namely,
bcolor()
,
bfcolor()
,
blcolor()
,
blwidth()
,and
blpattern()
. See
Twoway : Range

and [

(scatter ownhome pcturban80)
The
ciplot()
option can be used to
select a different command for
displaying the confidence interval. The
default command is
twoway rarea
and
can be selected via the
ciplot(rarea)
option. Here, we use the
ciplot(rline)
option, which displays
the confidence interval as two lines
without any filled area. The valid
options include
rarea
,
rbar
,
rspike
,
rcap
,
rcapsym
,
rscatter
,
rline
,and
rconnected
.

By choosing the
rline
command for
displaying the confidence interval, we
can then use options appropriate for
the
twoway rline
command. Here, we
make the line green, dashed, and thick.
