Joe Abramson has developed an augmented Windows version (WINPEPI)
of the PEPI suite of programs for epidemiologists. You can
read a description of WINPEPI (published in Epidemiologic
Perspectives & Innovations) by clicking here. A list of currently available functions and procedures is available here.
The last update (version 10.7) was posted to this site on July 24,
2010.
Download the
latest version of WINPEPI as an executable (.EXE) file (5.2 mb).
The downloaded file will be WinPepiSetup.exe. Alternatively, you
can download it in a ZIP archive :
Download the
latest version of WINPEPI as a .ZIP archive (5.2 mb)
which you will have to open to access WinPepiSetup.exe.
When you run WinPepiSetup.exe, it will install the latest WINPEPI
programs and manuals, and an index to the statistical procedures and programs,
in any folder you select. Older versions will be replaced. Follow the
instructions, and your desktop will have a portal to the programs and manuals,
the index, and relevant Internet sites.
No changes are made to the Windows registry.
As a third alternative, if
you do not have permission to use an installation program (but can download
executable files in a zip file), download WinPepiFiles.zip, which
contains all the components of WINPEPI, but no installation program. You will
have to open this zip file and copy its contents to a directory of your choice
(overwriting any previous versions), and manually put a shortcut to winpepi.exe
(the portal program) on your desktop.
Download
the WINPEPI files in a ZIP archive (without an installation program) (7.0 mb).
All the programs are now 32-bit applications, and will run in any
version of Microsoft Windows (including Vista) except Windows 3.
A report from the McAfee Site Advisor confirms that Winpepi and other
software offered on this web-site are "free of adware, spyware and other
potentially unwanted programs".
RECENT ADDITIONS
The main recent additions are: Indicators of discriminatory power of
logistic models (LOGISTIC ver.
1.35); measure of disagreement
between matched numerical observations (Costa-Cantoz) (PAIRSetc ver.
2.44); Brunner-Munzel test for
comparison of ordered categories (COMPARE2 ver. 2.43);
calibration of P values to compute Bayesian minimum posterior
probabilities of the null hypothesis (WHATIS ver. 4.51); estimation of risk
ratios, risk differences, and NNT from logistic regression results (LOGISTIC
ver. 1.33); Linn and Grunau's predictive summary index for clinical tests
(DESCRIBE ver. 2.19); Bayesian CIs for indices of positive and negative
agreement (PAIRSetc ver. 2.29); monotonic regression analysis (PAIRSetc ver. 2.35); and enhanced procedures for
multiple comparisons of numerical samples (ETCETERA ver.2.32)
Other recent enhancements include: probit analysis and a nonparametric
counterpart, analysis of factorial design and crossover trials; appraisal of
agreement between 3 or more rankings; sensitivity analysis to appraise the
effect of unmeasured confounders;
computation of Bayes factors;
simple and multiple linear regression; comparison of 3 or more dependent
or independent samples; median polish or mean polish of two-way tables;
improved meta-analytic procedures for diagnostic and screening tests; and
drawing of forest plots.
A fuller list of recent changes is provided in pepinews.txt,
which is included in this download.
To avoid problems with administrator rights in Vista and Windows 7, all
results are now automatically saved in PEPI.TXT in the Winpepi folder, instead
of in C:\PEPI.TXT, where older results may be found.
The currently available WINPEPI programs are :
COMPARE2.EXE - For comparisons of two independent groups
or samples. The current version number is 2.43.
DESCRIBE.EXE - For use in descriptive epidemiology
including the appraisal of separate samples in comparative studies. The current
version number is 2.24.
ETCETERA.EXE - Miscellaneous (randomization, random
sampling, adjustment of multiple-test p-values, appraisal of synergism,
assessment of a scale, correlation-coefficient tools, large contingency tables,
three-way tables, median polish and mean polish, appraisal of effect of
unmeasured confounders). The current version number is 2.33.
LOGISTIC.EXE - Multiple logistic regression. The current
version number is 1.35.
PAIRSetc.EXE - For appraisal of differences and
agreement between matched samples or observations. The current version number
is 2.44.
POISSON.EXE - Multiple Poisson regression. The current
version number is 1.24.
WHATIS.EXE - An expression evaluator (with storage of
constants, interim results, and formulae) and calculator for p values (and
their inverse), confidence intervals, and time spans. The current version
number is 4.54.
Manuals are supplied in PDF format, which can be read with (e.g.) Foxit Reader or the Adobe Acrobat Reader.
