Analytic Tools

An incredible open-source math tool that leverages Python (MatPlotLib for graphing and NumPy for numerical work) and R (for statistical analysis).   Ref:  https://www.sagemath.org

R is the gold standard for all forms of statistical analysis.  A tool with these capabilities is essential for serious statistical analysis of large data sets.  Ref: https://www.r-project.org/

Covers basics of the language, user defined functions and simple classes.  Additionally, Numerical Python (NumPy) has a wide range of capabilities for computational analysis.  Ref: https://www.python.org/  and  https://numpy.org/
