Lisp-Stat is an environment for statistical computing, conceptually similar to R, that is also suitable for front-line production deployment of machine learning and statistical models. It grew out of a desire to have an environment for rapidly prototyping analytical and AI solutions, and move to production environments with minimal friction. It includes high accuracy statistical and mathematical functions, derived from the same sources as SciPy, a data frame implementation similar to Tidyverse/R and high quality interactive graphics via Vega-Lite
