All programs presented here are free and open source softwareThe users have the freedom to run, copy, distribute, study, change and improve the software. We defend these freedoms because everyone deserves them. With these freedoms, the users (both individually and collectively) control the program and what it does for them. In contrast the nonfree program controls the users, and the developer controls the program; this makes the program an instrument of unjust power.

PAC was designed in the 1980s by Jacques Poitevineau,
in collaboration with Bruno Lecoutre for the statistical part itself.
It was written by Jacques Poitevineau in the FORTRAN 90 standard.
The subroutines are original, with the exception of a few from libraries.
LINPACK/EISPACK, and some mathematical functions.
like betacdf. f90 (when this is the case, the origin is indicated by comments in the source).
Originally, PAC was designed to run alone on most platforms in console mode. PAC consists of two main subsets: 1) The GMP subset (for Groupe Mathématiques et Psychologie). The purpose of the subprograms in this subset is the general processing of data (how many variables, their characteristics), What are the names to be given to variables, the name of the input data file, etc.? 2) The PAC subset that performs statistical analyses Each of these subsets uses the ANACOM7 toolbox (ANAlyse des COMmandes) for the analysis of user commands. The structure and syntax of these commands, as well as some aspects of the program's organization, were inspired by BMDP software. |
LePAC was originally a user-friendly Windows interface for running
PAC.
Other programmes have been gradually included: ![]() ![]() ![]() ![]() ![]() ![]() ![]() |
LePAC was written in Visual Basic by Bruno Lecoutre. Jacques Poitevineau wrote many functions in FORTRAN. |
