twoway (lfitci ownhome pcturban80, stdf
level(90)
)
(scatter ownhome pcturban80)
We can use the
level()
option to set
the confidence level for the confidence
interval. Here, we make the confidence
level 90%.

twoway (lfitci ownhome pcturban80,

)
(scatter ownhome pcturban80)
We now look at how you can control
the display of the fit line. We can use
the
nofit
option to suppress the
display of the fit line. Note that we
have switched to the
vg brite
scheme
for a different look for the graphs.

twoway (lfitci ownhome pcturban80,

)
(scatter ownhome pcturban80)
You can supply options like
connect()
,
clpattern()
(connect line pattern),
clwidth()
(connect line width), and
clcolor()
(connect line color) to
control how the fit line will be
displayed. Here, we use the
clpattern(dash)
and
clwidth(thick)
options to make the fit line dashed and
thick. See
Options : Connecting

more details.
