LuaLaTeX Regression

A system for performing regression testing on CSV format data files in LaTeX, written purely in Lua for use with LuaLaTeX. Includes the ability to fit polynomials of multiple orders to data, and plot the results using PGFPlots. Offers some additional features such as the ability to generate confidence intervals and perform $R^2$ tests on the data.
