st: RE: Confidence Intervals plot
Questions of the form "I tried such-and-such
a program, but it didn't produce what I want"
are pretty difficult to answer, especially
if you are fuzzy on what you want.
The programmer is inclined to say, "Well,
feel free to write your own program then!"
-ciplot- is a program on SSC I wrote.
Your reference to -ecplot- I take to mean
one to -eclplot- by Roger Newson.
-ciplot- is a wrapper for -ci-, as its help
explains. I am not clear, as you do not say,
whether you would expect -ci- to produce
your confidence intervals. But if you don't
then -eclplot- should be fine for your purpose.
In general, confidence intervals plots
* the way you like them *
are easy. What is difficult for a
programmer is to prepare for all the ways that
people like them. In your case, you would need
calculate your quintile groups
calculate your confidence intervals
decide on how to represent estimates, e.g.
-scatter- or -twoway bar-
decide on how to represent limits, e.g.
Then a typical plot requires an overlay
twoway ... || ...
Further advice would require a more precise
