Statistical modeling and analysis tools are required for getting insights into various matters about a business, health, education, etc. Performing statistical analysis and advanced calculations on a large number of data can be a tedious task. The statistical analysis tools help ease the matter by providing efficient automatic means through which unique stats and complex calculations to draw various insights from a significant amount of data can be generated in no time. Here in this article, we discuss the statistical and econometric analysis tools that are widely adopted by many statistics fields’ experts and numerous Linux-based organizations. The tools discussed here are all free, open-source, and cross-platform compatible and are most optimal for Linux-based systems.
The R Project for Statistical Computing and analysis is a free, open-source, and cross-platform compatible statistical modeling solution by R Studio. R Studio was released in 2011 and comes under the Affero General Public version 3 License. The efficient and enhanced solution provides an environment and a platform for statistical graphics creations, computing, and analysis. R Project for Statistical Computing runs most efficiently with the R Studio paradigm. With R Project, users can perform a variety of statistical modeling tasks, perform data manipulation, intermediate tools for statistical programming, and data analysis, graphical display, flawlessly designed plots, which include mathematical symbols, conditional loops, and mathematical calculations. Being open-source and supporting a large community, more advanced features and functionalities can be added and are added by R Studio’s active community now and then which enhances the scope and reliability of the platform.
