Winpepi

WINPEPI
WinPepi is a freeware package of statistical programs for epidemiologists, comprising seven programs with over 100 modules. WinPepi is not a complete compendium of statistical routines for epidemiologists. but it provides a very wide range of procedures, including those most commonly used and many that are not easy to find elsewhere. This has repeatedly led reviewers to use a "Swiss army knife" analogy. Each program has a comprehensive fully-referenced manual.

WinPepi had its origins in 1983 in a book of programs for hand-held calculators, which in 1993 developed into a set of DOS-based computer programs that came to be called Pepi (an acronym for "Programs for EPIdemiologists") and evolved, after its fourth version in 2001, into WinPepi (Pepi-for-Windows). WinPepi is still a work in progress, and new expanded versions are issued at frequent intervals.

The programs are notable for their user-friendliness. A portal provides immediate access to all the programs and manuals, and to an alphabetical index that pinpoints the programs and modules to be used for specific purposes. Menus, buttons, on-screen instructions, help screens, pop-up hints, and built-in error traps make the programs easy to use.

WinPepi does not provide data management facilities. With some exceptions, it requires the entry (at the keyboard or by pasting) of data that have already been counted or summarized.
