Programming with Big Data in R (pbdR) – a series of R packages enhanced by SPMD parallelism for big data analysis R Commander – GUI interface for R Rattle GUI – GUI interface for R Revolution Analytics – production-grade software for the enterprise big data analytics RStudio – GUI interface and development environment for R ROOT – an open-source C++ system for data storage, processing and analysis, developed by CERN and used to find the Higgs boson Salstat – menu-driven statistics software Scilab – uses GPL-compatible CeCILL license SciPy – Python library for scientific computing that contains the stats sub-package which is partly based on the venerable |STAT (a.k.a. PipeStat, formerly UNIX|STAT) software scikit-learn – extends SciPy with a host of machine learning models (classification, clustering, regression, etc.) statsmodels – extends SciPy with statistical models and tests (regression, plotting, example datasets, generalized linear model (GLM), time series analysis, autoregressive–moving-average model (ARMA), vector autoregression (VAR), non-parametric statistics, ANOVA, empirical likelihood) Shogun (toolbox) – open-source, large-scale machine learning toolbox that provides several SVM (Support Vector Machine) implementations (like libSVM, SVMlight) under a common framework and interfaces to Octave, MATLAB, Python, R Simfit – simulation, curve fitting, statistics, and plotting SOCR SOFA Statistics – desktop GUI program focused on ease of use, learn as you go, and beautiful output Stan (software) – open-source package for obtaining Bayesian inference using the No-U-Turn sampler, a variant of Hamiltonian Monte Carlo. It is somewhat like BUGS, but with a different language for expressing models and a different sampler for sampling from their posteriors Statistical Lab – R-based and focusing on educational purposes TOPCAT (software) – interactive graphical analysis and manipulation package for astronomers that understands FITS, VOTable and CDF formats. Torch (machine learning) – a deep learning software library written in Lua (programming language) Weka (machine learning) – a suite of machine learning software written at the University of Waikato Public domain CSPro (core is public domain but without publicly available source code; the web UI has been open sourced under Apache version 2 and the help system under GPL version 3) Dataplot (NIST) X-13ARIMA-SEATS (public domain in the United States only; outside of the United States is under US government copyright) Freeware BV4.1 GeoDA MaxStat Lite – general statistical software MINUIT WinBUGS – Bayesian analysis using Markov chain Monte Carlo methods Winpepi – package of statistical programs for epidemiologists Proprietary Alteryx – analytics platform with
