ADDATI (Analisi Dei DATI: Data Analysis)  for Windows 32 is a set of Multivariate Analysis routines mostly, but not exclusively, aimed at territorial applications. It can friendly and easily compute distributions of variables, cross-tabulate categorical variables, compute tables of correlations, carry out Principal Components Analyses, Analyses of the Correspondences, non-hierarchical Clustering. New variables/indicators can be computed via various options. Projections of variables and statistical units on the most relevant factorial planes can be visualised, in order to interpret the results of factorial analyses, etc. The previous versions of ADDATI (Analisi Dei DATI, Data Analysis), up to version 4, were DOS-based. Developed at the University IUAV of Venice, they have been extensively used in Italy by University Departments, Reasearch Institutes and Public Agencies. The first English version (v. 3.1) was developed in 1990-93 in the frame of the Project FAO/GCPS/RAF/256/ITA. It was used by some FAO Projects and by the VAM (Vulnerability Analysis and Mapping) unit of the World Food Program, which also supported the development of versions 5. These (the last was v. 5.2d) were Win32/DOS mixed versions, that re-wrote as Win32 applications only some of the programmes included in the package, in particular FACPLAN, the graphic utility used to display the proiections onto factorial planes. The last DOS/Windows version, v. 5.2d, is still available for downloading, just in case... (see below). This version 6, still in progress and renamed ADDAWIN (ADDATI for WINdows) is fully Win32 and runs under all Windows versions.  It is much more friendly and didactic, capable of processing very large Data Sets  and helping the user in the inspection of data features. Initially written only in Italian, it was tested for two-three years in some Courses at the University IUAV of Venice. The initial version enabled the user to perform in a very easy way some uni- or bi-variate operations (variables' distributions, singling out of outliers, construction of new indicators, crosstabulations, tables of correlations, etc.). Since June 2006 also some factorial analyses have been added (Principal Components Analysis, Analysis of  the Correspondences, non-hierarchical Clustering). After some years of use and misuse by my students, whom I thank fro giving me the occasion to trap and fix a significant number of bugs, the package appeared ready to be distributed. The ODA (Operation Department - Assessment, Analysis & Preparedness) division of the World Food Program, that makes some use of it in its analyses of poverty and vulnerability, offered to support the preparation of an English version, and here it is, finally. The English version of the User's Manual is not yet complete (some chapters are available below), but the online help is quite rich, and offers all that is necessary.   Installation Extract the contents of the zipped archive to a dedicated folder (e.g., C:\ADDAWIN, but any name and path are OK; anyway, better not on the desktop, to keep control of where the files stay, specially in case of update). Run the programme by double-clicking on the file ADDAWIN.EXE. The present version, still experimental, has a multilingual structure. At the time being it supports English and Italian, but more languages can be easily added, if there is any interest in it. At the first run, the default language is English. It can be easily changed by choosing from the Menu the option File→Settings. The new language is immediately operational on all aspects of the programme (interface, help on line, ancillary applications).      Download    The package can be freely used for any didactic, research or professional purpose. As a reward for his work, the author would appreciate the use of the package to be acknowledged in publications or in the programs of Courses that take advantage of it.   This zipped archive (1.94 MB) installs the full Italian/English version of ADDAWIN, updated on December 17, 2008. The file includes anything needed to install, in particular some dynamic libraries (DLLs), ancillary applications, help files, etc., necessary for a successful execution.  Such elements seldom change over versions, and it is useless to re-download them. Therefore, this file should be used only for the first installation,  or to update a quite old version.       To update the immediately preceding version, it is better to download this smaller zipped file available at the date of the last update. It includes only the files that have been modified: they must be expanded in the ADDAWIN folder, overwriting those with the same name already existing there.       (4.1 MB) The archive contains some Datasets (*.DAT, *.CSV and *.TXT files) to allow the user to practice with the programme and with the structure of the documentation files associated with the data. It also includes a file .FPL, just to offer an example of visualization of the projections onto factorial planes. Expand the file to a dedicated folder and read the instructions in the file <note.rtf>, included.     Problems with the help online? ADDAWIN offers an online help both in HTML and WINHELP format. The user can choose from the Configuration dialog which of them to use. However, as Windows Vista and Windows7 no longer support the Winhelp format, the use of the HTML format (the extension of the help file is .CHM) is practically compulsory. A Vista or Windows7 user who prefers the .HLP format should download the WINHELP application from the Microsoft site, and install it. In case, not only for ADDAWIN but also for other applications offering only a .HLP help,  download here below the file appropriate for your Operational System (Vista or Win7), which can then be run to manage the installation of  WinHlp32 from the Microsoft site.             The Italian ADDAWIN manual is ready, the English one is still on preparation. However, as some chapters are finished, they are offered here for downloading, together with the Kenya Dataset used in the example discussed on the chapters on Principal Components Analysis and non-hierarchical Clustering. For those who still might need some functions present in the old Dos-Windows version 5.2, and no longer supported in the new one, this is the link to download it.   See the recent changes and the bugs fixed

Warning! This is still a Beta version. All users who trip over a bug, or what appears to be a 'strange' behavior, are kindly requested to inform the author writing to silvio@iuav.it  and providing as much detailed information as possible. A copy of the Data Set, and a description of the operation that resulted in an error would be useful. Thanks.
