Statistics in Python (SiPy): Python-Based Statistical Graphical User Interface for Python/R/Julia

SiPy is a free, plugin-extensible statistical interface that brings Python (SciPy/pandas), R, and Julia backends to end-users without requiring programming knowledge. It is designed to occupy the underserved quadrant of statistical tools that are simultaneously free and easy to use, and is available as a command-line shell, a Jupyter kernel, and a portable Windows application.
