Date   Wed, 23 Jul 2003 17:02:39 +0100

Fellow Statalisters:

Thanks to Kit Baum, there are now new versions of the -eclplot- and -smileplot- packages. In Stata, type -ssc desc eclplot- and -ssc desc smileplot- to find out more.

The -eclplot- and -smileplot- packages create Stata 8 plots of confidence intervals and P-values, respectively. They are described as below on my website. The new versions fix a bug, common to both packages, which very occasionally caused them to crash while attempting to draw graphics, if their graphics options or suboptions contained quoted strings. This bug has now been fixed in both packages.

Best wishes

Roger

package eclplot from http://www.kcl-phs.org.uk/rogernewson/stata8

TITLE
eclplot: Horizontal and vertical confidence interval plots

DESCRIPTION/AUTHOR(S)
eclplot creates a plot of estimates with lower and upper confidence limits
on one axis against another numeric variable on the other axis. The estimates
and lower and upper confidence limits are stored in three variables, in a
data set with one observation per confidence interval to be plotted. Data
sets with such variables may be created by the parmest package, or by statsby
or postfile in official Stata. The user has a choice of plotting the
confidence intervals horizontally or vertically, and a choice of range plot
styles for the confidence intervals, and may also overlay the confidence
interval plot with other plots using the plot option. In default, eclplot
does not print a legend, and has "sensible" settings for axis titles and
labels, but these defaults may be overridden by the user.

package smileplot from http://www.kcl-phs.org.uk/rogernewson/stata8
----------------------------------------------------------------------------------------------------------------------------

TITLE
smileplot: Multiple test procedures and smile plots

DESCRIPTION/AUTHOR(S)
This package contains the programs multproc, smileplot and smileplot7.
multproc inputs a data set with 1 observation for each of a set of multiple
significance tests and data on the P-values, and carries out a multiple test
procedure chosen by the user to define a corrected overall critical P-value
for accepting or rejecting the null hypotheses tested. These procedures
may be one-step, step-up or step-down, and may control the familywise error
rate (eg the Bonferroni, Sidak, Holm, Holland-Copenhaver, Hochberg and Rom
procedures) or the false discovery rate (eg the Simes, Benjamini-Liu,
Benjamini-Yekutieli and Benjamini-Krieger-Yekutieli procedures). smileplot,
and its Stata 7 version smileplot7, work by calling multproc and then
creating a smile plot, with data points corresponding to multiple estimated
parameters, the P-values (on a reverse log scale) on the Y-axis, and the
corresponding parameter estimates (or another variable) on the X-axis. There
are Y-axis reference lines at the uncorrected and corrected overall critical
P-values. The reference line at the corrected critical P-value, known as the
parapet line, is interpreted informally as a boundary between data mining and
data dredging. multproc, smileplot and smileplot7 are used on data sets with
one observation per estimated parameter and data on estimates and their
P-values, which may be created using parmby, parmest, statsby or postfile.
