Please can you tell me if there is a simple way to produce a plot of the
output from proportion <dependent var>, over(<categorical variable>)
So the graph should show the percentage, within each category, of the
dependent variable - rather than the overall percentage in each category.
-------------------------------------------------------------
I use -ci- to generate the proportions with confidence intervals.
The variable -low- is coded 0/1, so its mean is the proportion of 1s.
-statsby- generates a new dataset with proportions and confidence
intervals; conversion to percentages is simple:
. webuse lbw
. statsby proportion=r(mean) lb=r(lb) ub=r(ub), by(race) clear : ci low, binomial
. list
+----------------------------------------+
| race propor~n lb ub |
|----------------------------------------|
1. | white .2395833 .1583384 .3374935 |
2. | black .4230769 .233522 .6308196 |
3. | other .3731343 .2579742 .4998952 |

Hope this helps
