Statistical software

R: is a free software environment for statistical computing and graphics. It compiles and runs on a wide variety of UNIX platforms, Windows and MacOS. To download R, please choose your preferred CRAN mirror.

gretl: Is a cross-platform software package for econometric analysis, written in the C programming language. It is free, open-source software. You may redistribute it and/or modify it under the terms of the GNU General Public License (GPL) as published by the Free Software Foundation.

Octave: is a high-level interpreted language, primarily intended for numerical computations. It provides capabilities for the numerical solution of linear and nonlinear problems, and for performing other numerical experiments. It also provides extensive graphics capabilities for data visualization and manipulation. Octave is normally used through its interactive command line interface, but it can also be used to write non-interactive programs. The Octave language is quite similar to Matlab so that most programs are easily portable.

pspp: PSPP is a program for statistical analysis of sampled data. It is a Free replacement for the proprietary program SPSS, and appears very similar to it with a few exceptions. PSPP can perform descriptive statistics, T-tests, linear regression and non-parametric tests. Its backend is designed to perform its analyses as fast as possible, regardless of the size of the input data. You can use PSPP with its graphical interface or the more traditional syntax commands.

SciLab: is an open source, cross-platform numerical computational package and a high-level, numerically oriented programming language. It can be used for signal processing, statistical analysis, image enhancement, fluid dynamics simulations, numerical optimization, and modeling and simulation of explicit and implicit dynamical systems. MATLAB code, which is similar in syntax, can be converted to Scilab. Scilab is one of several open source alternatives to MATLAB.

Operating systems

Linux foundation: The Linux Foundation is a non-profit consortium dedicated to fostering the growth of Linux.

Ubuntu: the Ubuntu operating system powers millions of desktops, netbooks and servers around the world. Ubuntu does everything you need it to. It'll work with your existing PC files, printers, cameras and MP3 players. And it comes with thousands of free apps.

Xubuntu: Xubuntu is a community developed, Ubuntu-based Linux operating system.Xubuntu is an elegant and easy-to-use operating system. Xubuntu comes with Xfce, which is a stable, light and configurable desktop environment.Xubuntu is perfect for those who want the most out of their desktops, laptops and netbooks with a modern look and enough features for efficient, daily usage. It works well on older hardware too. This is my preferred distribution: fast, simple, and reliable.

Top 10 Linux distributions: This page lists 10 Linux distributions (plus an honourable mention of FreeBSD, by far the most popular of all of the BSDs), which are generally considered as most widely-used by Linux users around the world.

Office suites

It is available in many languages and works on all common computers. It stores all your data in an international open standard format and can also read and write files from other common office software packages. It can be downloaded and used completely free of charge for any purpose.

LaTeX

TexLIve: TeX Live is an easy way to get up and running with the TeX document production system. It provides a comprehensive TeX system with binaries for most flavors of Unix, including GNU/Linux, and also Windows. It includes all the major TeX-related programs, macro packages, and fonts that are free software, including support for many languages around the world. (By the way, this is my favourite distribution.)

Tex Maker: Texmaker is a free, modern and cross-platform LaTeX editor for linux, macosx and windows systems that integrates many tools needed to develop documents with LaTeX, in just one application. Texmaker includes unicode support, spell checking, auto-completion, code folding and a built-in pdf viewer with synctex support and continuous view mode. Texmaker is easy to use and to configure. Texmaker is released under the GPL license .

CTAN: The Comprehensive TeX Archive Network is the place to get materials related to the TeX typesetting system.

Documents & Research papers

RePEc (Research Papers in Economics) is a collaborative effort of hundreds of volunteers in 75 countries to enhance the dissemination of research in economics. The heart of the project is a decentralized database of working papers, journal articles and software components. All RePEc material is freely available.

University of Molise Economics and Statistics Discussion Papers: The Economics & Statistics Discussion Papers are preliminary materials circulated to stimulate discussion and critical comment.

SCImago Journal & Country Rank: is a portal that includes the journals and country scientific indicators developed from the information contained in the Scopus® database. These indicators can be used to assess and analyze scientific domains.

SCImago Institutions Rankings yearly publishes rankings of Worldwide Research Institutions.
