Thanks to Kit Baum, the -distplot- package has been revised
on SSC for Stata 8. -distplot- is for cumulative (probability
or frequency) distribution plots.
Type
ssc describe distplot
or
ssc install distplot
or
ssc install distplot, replace
if and as desired in Stata 8. If you have Stata 7,
then the previous version of -distplot- on SSC
remains there, cloned as -distplot7-.
If you have Stata 6, then an earlier version
of -distplot- is downloadable from the files
for STB-51 (type -search distplot-).
This revision is more than a minimal revision
of -distplot- so that the graphics produced
use those of Stata 8. A few features which seemed
idiosyncratic or minor have been removed.
Some features which were implemented in
the -ordplot- package have been implemented in
a more general form in -distplot-. -ordplot-
remains on SSC for version 6.0 up, but will not
be further developed, at least by me.
The main features of -distplot- are
* support for showing distributions for groups of
a single variable
* support for showing distributions for several
variables
* support for fweights and aweights
* support for different plottypes. The syntax
starts
distplot plottype
where plottype is one of area, bar, connected,
dot, dropline, line, scatter or spike. Most
users will probably decide that only about
three of these are at all useful, but the
flexibility is there, courtesy of the design
of -twoway-.
* support for showing cumulative frequency
as well as cumulative probability
* support for reverse distributions
* support for showing probability
or frequency on any user-chosen transformed scale
(providing transformation can be
expressed as an expression in Stata)
